Numbers on signs are getting profanity filtered (Profanity filter is off)

I am building in my creative world its a city world and naturally I am numbering my buildings as a part of this. Recently as I have been numbering these buildings after ever 3rd sign it has started to filter out all numbers. This includes ones that are not considered ‘naughty’ or ‘bad’. My first solution was to shut off the profanity filter so i did. However the profanity filter is continuing to filter out numbers even though it is shut off and has perssisted passed this point.
