To reproduce the bug:
In creative mode, pick a crafting table
Open the crafting table user interface
Place any item in any of crafting table's slots
Place the same item to the same slot again
The item won't be removed/replaced by any means unless reopened the map
That item persists to appear in any other crafting table user interface after that point
