Hello Swiss

You should go to your profile on forums and click on "Summary" under the "Game Account" and login trough there so your account gets linked. And then click on settings and change your name there.

The linking in-game hasn't been updated yet, it is still using the old version so it assumes your account is linked. Simply link it through the website.
