Using chekboxes on a recyclerview with firebase [duplicate]

How can you create a proper recycler view with CheckBox using firebase, currently I can create 5 viewHolders and everythings goes fine, when I create 6 or more viewHolder the checkboxes start checking at random. Has anyone done something similar to this? Any help would be highly appreciated!!

Currently this is my OnBindViewHolder:

public void onBindViewHolder(@NonNull final MyViewHolder holder, int position){

       final Habitos habitos = mHabitosList.get(position);

 holder.nombre.setText(habitos.getNombre());

            FirebaseDatabase mDatabase = FirebaseDatabase.getInstance();
            mDatabaseReference = mDatabase.getReference("Habitos");
            FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
            if(user != null) {
                userId = user.getUid();
                habitosReference = mDatabaseReference.child(userId);
                Focus focus = new Focus();
                mDays = focus.getPrevFiveDaysNumbers();
                habitosId = mHabitosList.get(position).getHabitosId();

                habitosReference.child(habitosId).child("checks").addValueEventListener(new ValueEventListener() {
                    @Override
                    public void onDataChange(DataSnapshot dataSnapshot) {
                            mChecks = (HashMap<String, Boolean>) dataSnapshot.getValue();
                            Log.d("Checky", mChecks+"");
                            assert mChecks != null;
                           checkBox1 = mChecks.get(mDays[0]);
                            checkBox2 = mChecks.get(mDays[1]);
                            checkBox3 = mChecks.get(mDays[2]);
                            checkBox4 = mChecks.get(mDays[3]);
                            checkBox5 = mChecks.get(mDays[4]);
                            checkListeners(holder, habitos);
                        }

                    @Override
                    public void onCancelled(DatabaseError databaseError) {

                    }
                });
    }

And to listen to the checkboxes I have the following method:

private void checkListeners(MyViewHolder holder, final Habitos habitos) {
        holder.CB1.setChecked(checkBox1);
        holder.CB1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {

                String HabitosId = habitos.getHabitosId();
                int total = habitos.getTotal();
                if (b) {
                    habitosReference.child(HabitosId).child("checks").child(mDays[0]).setValue(true);
                    total++;
                } else {
                    habitosReference.child(HabitosId).child("checks").child(mDays[0]).setValue(false);
                    total--;
                }
                habitosReference.child(HabitosId).child("total").setValue(total);
            }
        });

This adds a +1 value everytime a checkbox is checked. Everything is working fine except when I add more than 5 viewHolders. Any idea how could I fix this?
