My certificate has my name wrong

When I try to edit my name in my profile, your site returns an error:

Enter a valid username. This value may contain only letters, numbers, and @/./+/-/_ characters.

I didn’t change the username, (Joseph Sloan_68624) and I didn’t choose it. You did.

Please advise.
