I had the problem once too...
But if i remember correctly it was just tracked somehow wrong. I also had sessions tracked which i never played...
As I see on your screenshot you reserved your name... If you did so, you can click on "Reserve name" again and choose "Playlock" there.
That would help in anyways
Übrigens: Alles Gute zum Geburtstag nachträglich

Hoffe du hast ordentlich gefeiert ^^
