check of checkbox checks 2 checkboxes

I have a custom listadapter (extends baseAdapter) en in those list items I have a checkbox.

Now when I click on de listitem the checkbox gets checked. But if I would check the first item, the 4th/5th item also gets checked. But the first item, which I actually click on gets stored in the database, which is right. But the 5th doesn't. And if I revisit that activity the first item gets loaded in because he was stored in de db, but also that 5th gets loaded in :O AND I JUST CANT FIND OUT WHY.. So Annoying! So I hope one of you can help me out here..

My IndicatorListAdapter.java

package nl.webdesignwiljan.exp.adapters;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.TextView;

import nl.webdesignwiljan.exp.models.Indicator;
import nl.webdesignwiljan.exp.R;
import nl.webdesignwiljan.exp.models.UserIndicator;

public class IndicatorListAdapter extends BaseAdapter {

    private Context mContext;
    private Indicator[] mIndicatoren;
    private UserIndicator[] mUserIndicatoren;

    public IndicatorListAdapter(Context context, Indicator[] indicators, UserIndicator[] userIndicatoren) {
        mContext = context;
        mIndicatoren = indicators;
        mUserIndicatoren = userIndicatoren;
    }

    @Override
    public int getCount() {
        return mIndicatoren.length;
    }

    @Override
    public Object getItem(int position) {
        return mIndicatoren[position];
    }

    @Override
    public long getItemId(int position) {
        return 0; // Not going to use
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;

        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.indicator_item, null);
            holder = new ViewHolder();
            holder.indicatorItemLabel = (TextView) convertView.findViewById(R.id.indicatorItemLabel);
            holder.indicatorCheckbox = (CheckBox) convertView.findViewById(R.id.checkBox);

            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        String title = position + " : " + mIndicatoren[position].getDesc();
        holder.indicatorItemLabel.setText(title);

        // TODO: LOAD THE CHECK-VALUE FROM THE USERINDICATORS IN

        for (UserIndicator userIndicatoren : mUserIndicatoren) {
            // Check is the current userIndicator and indicator are the same
            if (userIndicatoren.getIndicatorId() == mIndicatoren[position].getId()) {
                holder.indicatorCheckbox.setChecked(userIndicatoren.isCheck());
            }
        }
        return convertView;
    }

    public void updateSource(UserIndicator[] userIndicatoren, Indicator[] indicators) {
        mUserIndicatoren = userIndicatoren;
        mIndicatoren = indicators;
    }

    private static class ViewHolder {
        CheckBox indicatorCheckbox;
        TextView indicatorItemLabel;

    }
}

The Indicators are the data (like description) and the UserIndicators are the values if they are checked, attached to a user and also to a indicator. So I check after the TODO if a indicator is the same as a UserIndicator and then load in the checked value.

Here is my onClickListener with storing the values in the DB:

     // When clicking on a list item
            indicatorList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                                                     @Override
                                                     public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                 mCheckBox = ((CheckBox) view.findViewById(R.id.checkBox));

                 if (mCheckBox.isChecked()) {

                     // IF USER_INDICATOR NOT EXISTS -> CREATE NEW, ELSE UPDATE
                     // Exists
                     if (dataSource.readUserIndicator(mIndicators[position - 1].getId(), mSharedPreferences.getInt("userId", 0))) {
                         for (int i = 0; i < mUserIndicators.length; i++) {
                             if (mIndicators[position - 1].getId() == mUserIndicators[i].getIndicatorId()) {
                                 mUserIndicators[i].setCheck(false);

                                 // Update userIndicator
                                 dataSource.checkUserIndicator(mSharedPreferences.getInt("userId", 0), mIndicators[position - 1], mUserIndicators[i]);
                             }
                         }
                         // Does not exist
                     }
                 } else {
                     // Exists
                     if (dataSource.readUserIndicator(mIndicators[position - 1].getId(), mSharedPreferences.getInt("userId", 0))) {
                         for (int i = 0; i < mUserIndicators.length; i++) {
                             if (mIndicators[position - 1].getId() == mUserIndicators[i].getIndicatorId()) {
                                 mUserIndicators[i].setCheck(true);
                                 dataSource.checkUserIndicator(mSharedPreferences.getInt("userId", 0), mIndicators[position - 1], mUserIndicators[i]);
                             }
                         }
                         // Does not exist
                     } else {
                         UserIndicator userIndicator = new UserIndicator();
                         userIndicator.setCheck(true);
                         dataSource.createUserIndicator(mSharedPreferences.getInt("userId", 0), mIndicators[position - 1], userIndicator);
                         mUserIndicators = dataSource.readUserIndicators(mSharedPreferences.getInt("userId", 0));

                         // Search for the bijhorende indicator
                         for (int i = 0; i < mUserIndicators.length; i++) {
                             if (mUserIndicators[i].getIndicatorId() == mIndicators[position - 1].getId()) {
                                 mUserIndicators[i].setCheck(true);
                             }
                         }

                     }
                 }
                 indicatorListAdapter.updateSource(mUserIndicators, mIndicators);
                 indicatorListAdapter.notifyDataSetChanged();
             }

         });
