Thanks for asking, and welcome to the exchange! We prefer the version with the fandom name, even if it's not the canonical form. Because of the way AO3 organises tags, it's very possible for characters to become disconnected from their fandom, and the fandom name helps us put them back where they belong if that happens. You don't need to do anything :)
