Android reprocessing issue with animation

Question

I am trying to deploy maps in recyclerview. I got an expanding part of the work, but when adding a transition to it, some visual errors appear. Transitions work fine when there are no elements off the screen, but when I add more than (in my case) 4 elements to the recyclerview, it starts to occur.

The card extension works fine with more than four elements when I turn off transitional animation. I think the problem is related to changes in positions, but I can not find a solution to this problem.

The guide that I used to expand the map extension can be found here: https://stackoverflow.com/a/166778/

And my full recycliewiew adapter

public class BasketRecyclerAdapter extends RecyclerView.Adapter<BasketRecyclerAdapter.CustomViewHolder> {
private String letter;
private Context mContext;
private ColorGenerator generator = ColorGenerator.MATERIAL;
private List<Basket> baskets;
private int mExpandedPosition = -1;
private RecyclerView r1;

public BasketRecyclerAdapter(Context context, List<Basket> baskets, RecyclerView r1) {
    this.mContext = context;
    this.baskets = baskets;
    this.r1 = r1;

}

@Override
public CustomViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.basket_menu_item, null);
    CustomViewHolder viewHolder = new CustomViewHolder(view);
    return viewHolder;
}

@Override
public void onBindViewHolder(final BasketRecyclerAdapter.CustomViewHolder holder, final int position) {

    String basketName = baskets.get(position).getBasketName();

    holder.basketName.setText(basketName);

    letter = "" + basketName.charAt(0);

    TextDrawable drawable = TextDrawable.builder()
            .buildRound(letter, generator.getColor(basketName));


    holder.imageLetter.setImageDrawable(drawable);

    final boolean isExpanded = position == mExpandedPosition;
    holder.expandedLayout.setVisibility(isExpanded?View.VISIBLE:View.GONE);
    holder.itemView.setActivated(isExpanded);
    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mExpandedPosition = isExpanded ? -1:position;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                TransitionManager.beginDelayedTransition(r1);
            }
            notifyDataSetChanged();
        }
    });
