If I put a block item such as Block of Gold, Emerald, Hay Bale, Slime Block, into my crafting GUI and try to break it back into it's components, the items show in my crafting output but when I click on it, the items disappear and I  lose a block's worth. This has happened with every block item I've tried. I've tried clicking and dragging the item as well as shift clicking, and it always disappears. I'm unable to extract any of my ores or make gold nuggets or anything. This is happening on a Realm, it seems to work fine on a single player world.

Edited to add that this problem seems to have resolved itself.
