Sometimes a item is forever stuck in the crafting table even when you break it

So basically I have created a world, I am trying to build a decorative nether portal

i tried to craft a snord pottery and I accidentally did the wrong recipe so I tried to remove the sherds on the corner and it wouldn’t go away
i tried to break the crafting table and it would still be there

Edit - I have found the problem that does this when you replace a item from the crafting table with creative menu
