About stack items

I'm having problems with stack of items specifically elixir.
I did stack for pots and arrows and works perfectly.
but the elixir of the following happens:


if I pick over 1 elixir he joins normally but the slot was empty inventory that is unavailable for use again. and it gets worse when I teleport back all elixir for 1 in each slot.


anyone have idea how to solve this?
I'm fixing to stack 250
