Dropping items Bug - must move before dropping multiple items

So noticed today that if I drop multiple items (manually selecting or using tab select all) the items will all drop. If I attempt to drop another big group of items directly after I drop the previous ones, no matter how many I select, only one item drops from inventory (even though debug mode shows all items being ordered to drop). Only after moving one tile am I again able to drop more than one item.

Has anyone else seen this? I might have accidentally messed up some setting or something, but doesn’t really sound like something that settings would change. Any ideas on what I can do to fix it?
