Dolphin 7.1.6 + later - Facebook connect username

Facebook connect and the use of username

When a user uses Facebook connect the username is empty and the email datafield also. Is this only wrong in 7.1.6 or also in later version also?

Ist there a workaround? Because i cant even edit the useraccount as admin

To make it work it's better to update to the latest Dolphin version.
