[Gameplay] Shop Randomly Selling an Item from Inventory

An item gets sold from inventory when I'm in the shop sometimes. Happens when I click an item quickly to make the purchase and then close out of the shop. I have 4 clips with it happening to me but I've also seen reports of it happening and other threads. Not exactly sure how to reproduce it, but it happens once every 5-10 games to me.
