cencoring non curse words

So, i am working on an auction house in this server i am in, and i am trying to type in a book "rename your item to your discord username and add the minimum bid", but after i place it in the lectern it shows as "rename your item to #### ####### ######## and add the minimum bid"
I dont kmow why this happens but it is very annoying as even if i try to chamge your to ur, discord to discrd and username to name, it still censors them
