Whenever I select last one from list of RecyclerView,the I go upside then Previous one will also be selected and last one is selection is gone [duplicate]

I am using recyclerview it has 22 items in the list but whenever I select any item for downward or upward it will gone and a previously selected one appears because it recycled that view.

fun setData(dataList: ArrayList<Playerv2>?) { this.dataList = dataList }

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
    val view: View
    val mInflater = LayoutInflater.from(context)
    view = mInflater.inflate(R.layout.adapter_favourite_playerv2, parent, false)
    return FavouritePlayerViewHolder(view)
}

override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
    (holder as FavouritePlayerViewHolder).tvFavPlayerId.text = dataList?.get(position)?.shirtnumber.toString()
    holder.tvPlayerFirstName.text = dataList?.get(position)?.firstname + " " + dataList?.get(position)?.lastname
    holder.checkBox.text = dataList?.get(position)?.firstname + dataList?.get(position)?.lastname

    if (holder.checkBox.text.toString().equals(previouslySelectedOption, ignoreCase = true)) {
        holder.checkBox.isChecked = true
        lastCheckedCheckbox = holder.checkBox
        dataSelectedHolder(holder)
    } else {
        holder.checkBox.isChecked =
            false
        dataUnselectedHolder(holder)
    }
    holder.checkBox.text = ""


    holder.checkBox.setOnCheckedChangeListener { compoundButton, b ->
        if (lastCheckedCheckbox != null) {
            lastCheckedCheckbox?.isChecked = false
            lastCheckedCheckbox = null
            dataUnselectedHolder(holder)
        }
        if (holder.checkBox.isChecked) {
            lastCheckedCheckbox =
                holder.checkBox
            dataSelectedHolder(holder)
        }
        onRecyclerItemClicked.onItemClicked(dataList?.get(position)?.shirtnumber + ":" + dataList?.get(position)?.firstname + " " + dataList?.get(position)?.lastname)
    }
}

fun dataSelectedHolder(holder: FavouritePlayerViewHolder) {
    holder.tvPlayerFirstName.setTextColor(Color.RED)
    holder.tvFavPlayerId.setTextColor(Color.RED)
    holder.ConstraintbackgroundColor.setBackgroundResource(R.color.white)
}

fun dataUnselectedHolder(holder: FavouritePlayerViewHolder) {
    holder.tvFavPlayerId.setTextColor(Color.WHITE)
    holder.tvPlayerFirstName.setTextColor(Color.WHITE)
    holder.ConstraintbackgroundColor.setBackgroundResource(R.color.background_profile_color_0a2240)


    //Set imageView Here as well.
}

override fun getItemCount(): Int {
    return dataList!!.size
}

class FavouritePlayerViewHolder(itemView: View) :
    RecyclerView.ViewHolder(itemView) {
    var checkBox: CheckBox

    //        ImageView ivPlayerImage;
    var tvFavPlayerId: TextView
    var tvPlayerFirstName: TextView
    var tvFavPlayerLastName: TextView? = null
    var ConstraintbackgroundColor: ConstraintLayout

    init {
        checkBox = itemView.findViewById(R.id.cbFavPlayer)
        //            ivPlayerImage = itemView.findViewById(R.id.ivPlayerImage);
        tvFavPlayerId = itemView.findViewById(R.id.tvFavPlayerId)
        tvPlayerFirstName = itemView.findViewById(R.id.tvFavPlayerFirstName)
        ConstraintbackgroundColor = itemView.findViewById(R.id.ConstraintbackgroundColor)
    }
}

}

For Example, Previously I have selected the first option then I will select the last one in the list then I scrolled up and I see previously one is selected
