Name Change After Team Ban

I was banned for 7 days for my team's name, which surprised me because I've seen a lot worse, but I can't argue that although onsite and not obvious, it was kinda dirty.

Now that my ban is done, a message came up quickly when I went into CHEL about my name being inappropriate and telling me it's been changed but that I can change it myself to a non offensive one. But when I go in it will only let me change the nickname, abbreviation, description, etc. but it still says the random default club name with numbers

How can I change the team name to one of our own that's not offensive
