Glitched items in hand when trying to feed a llama

Pretty self-explanatory as bug but I'll link a video on youtube that showcases what is happening: https://youtu.be/pF6TkngsCUU

When I try to feed a llama, a portion of the stack of wheat or bays I'm using is glitched and reappaers when you switch item in the same spot (or simply right click on the empty spot where there was the stack of items)
