Smart stack not working right

Ok so i have noticed that when i have a smart stack of a said group of items like wood ect
it won’t let me drop a stack in the smart stack
But it will let me drop the whole smart stack

I can quick drop the individual stack but if i want to drop something i have to separate it so i can discard it from my inventory
I am a ps4 player
