My appointment listing page lists all appointments made, and the cb_attendance component of one element is changing that of other elements.

Error example: There are three scheduling elements, I set the first element to true and when I exit and return to the page the other two elements have their checkboxes changed to true.

I don't want the other checkboxes to change together, how to fix this?

The component that requires attention is the cb_attendance.

    public class ViewHolder extends RecyclerView.ViewHolder{
        EditText edt_id_scheduling, edt_date, edt_hour;
        AutoCompleteTextView act_area, act_service, act_Eprofessional, act_Eclient;
        CheckBox cb_attendance;
        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            edt_id_scheduling = itemView.findViewById(R.id.edt_id_scheduling);
