Drag does not return the expected from position

[ParryPatel021]

I am trying to fetch the from and to positions. But it does not return the expected positions.
I am using RecyclerView with GridLayoutManager.
If I drag image form 1st position to 3rd position, the library return fromPosition = 1 & toPosition = 2
But I want fromPosition = 0 & toPosition = 2

Any helps and suggestions are appreciated.
