RecyclerView-FlexibleDivider builder set showLastDivider to false by default，so the last item will have no divider. When app load more data, you called notifyItemRangedInserted and the item which has no divider will not be invalidated.

to fix the problem, here is my suggestions:

1. call notifyDatasetChanged when load more data to ensure all items are invalidated
2. build divider with showLastDivider
   new HorizontalDividerItemDecoration.Builder(this).showLastDivider().build());
3. call notifyItemChanged() to invalidate the item which has no divider
   final int last = adapter.getItemCount() - 1;
   // adaper.notifyItemRangeInserted(last, list.size());
   adapter.notifyItemChanged(last);

select one you prefer, i suggest the third one.
