Can't create new online franchises

I'm trying to start a new franchise with teambuilder. When I select "play online solo or multiplayer" and go to select the roster file, no matter which option I choose it gives me the message "You are already the commissioner of 20 leagues. Please delete one of your existing leagues before creating a new league." I am only in 2 franchises on this xbox but it still gives me this error message. I have found nothing online on how to fix it. Any ideas on how to fix it here?
