Do not know why it has to be censoring my items, I'm not even renaming them to anything profane, and even if I were, I feel I should get the choice for it to be censored or not. I saw another issue with this same problem that said it was resolved, but clearly not. There are also times where it takes back the item after renaming it, like it doesn't want me to change the item that that specific name. I've restarted my game and pc multiple times, also rolled back my realm, nothing fixed it. 

Update: Now when I go to put an enchanted book on an item, it changes the name of the item to ########, even if it's the default name. I am able to reset the item to the original name by deleting the ######## in an anvil and renaming it that way, which costs an extra level of xp.
