Probably just an error due to the recent website update. Of course, to assuage any worry you may have, you can check your current package on your profile, but this, among many other issues, will probably be fixed promptly.

I get the equivalent for my package, it's just a quirk of the way it's displayed on that screen, you're still a courtier though --check your account (click your name at the top of the screen), it should say "Current package: Courtier" on there.

Thanks for your time guys :)
