Desactivar marcas en texto

Morning!

I have a small and uncomfortable problem with some InDesign files, tiny but I'd like to stop seeing it. In some documents, I see "indications" in the text boxes and tables: spaces are turned into ·, periods into an inverted "P," and a # is added at the end of the text...

Got it, it's just a visual annoyance during editing that doesn't affect the export. I understand how those little quirks can be bothersome. Let's make them disappear! Anything else you need help with in relation to this issue?
