Сhanges in lists Collections.swap(mItems, fromPosition, toPosition) and notifyItemMoved(fromPosition, toPosition) not the same.

You can check it by calling recyclerView.getAdapter().notifyDataSetChanged(); in SimpleItemTouchHelperCallback#clearView()

My simple solution is:

String item = mItems.get(fromPosition);
expenditures.remove(fromPosition);
expenditures.add(toPosition, item);
