Items disappear when using recyclerview with ItemTouchHelper for drag & drop using FlexboxLayoutManager

[muzammilhussnain14]

I am trying to implement item reordering by drag and drop in a RecyclerView using FlexboxLayoutManager .
I attach ItemTouchHelper to my RecyclerView and than on function onItemMove I do following in my RecyclerView.AdapterImplementation

      override fun onMove(recyclerView: RecyclerView, fromVH: RecyclerView.ViewHolder, toVH: RecyclerView.ViewHolder){
        // swapping words in shuffled array
        Collections.swap(wordsShuffled, fromVH.adapterPosition, toVH.adapterPosition)
        // calling notify item moved to update UI
        notifyItemMoved(fromVH.adapterPosition, toVH.adapterPosition)
         //It messes up UI after notifyItemMoved some time few items disappear and sometime comeback in random order
    }

It messes up UI after notifyItemMoved some time few items disappear and sometime comeback in random order
