I had an Elytra i tried to put an enchanted book on it that was a multi-enchant book of Mending, Unbreaking 3, and Protection 4. The anvil glitched on me (I clicked output, it ate the xp but didnt give me the item). I clicked a second time on the output and it gave me the Elytra but they only had Mending and Unbreaking 3 on it (was missing Protection 4) richieh99 had tried to address the issue already but still unresolved atm as he was unable to use a command to add Prot 4.
I put the elytra in a chest at -43142, 53, -9075 on Northamerica in my town.
