Stonecutter just stopped working

this bug showed up initially in a realm. where i placed an item into a stonecutter. no matter what i click or shift click, im not getting the item. i then tested in a single player world, and it didnt work there either. the bug is not dependant on item as i discovered in single player testing.

(see footage below(it doesnt look like it but im actually clicking the items and even shift clicking))
