Newly written text disappearing, or being censored

Whenever I try to write text, regardless of platform I am playing on, the text ends up being either censored when it comes to renaming items or writing in a book and quill, or disappearing when writing text on signs. This issue is exclusive to the realm I run, and text works perfectly fine on single player worlds. I am not writing anything that would warrant a censorship, so this is very frustrating. A fix to this would be much appreciated.
