No Collection Progress on European Realm

Hello.
Whenever I play matches on the European Realm, I get no progress to my collection at all (which sucks, as I am european). Whenever I start the game on the american Realm, it shows me some progress, but it only for the games I play while the game was started on the american realm.

The first time I started the game, I accidently chose the american realm, this may be connected?

While I am playing on the european Realm, I cannot get invited to custom game lobbys. This may or may not be connected, I will also open a seperate thread for this.

I have tried reinstalling the game and even reinstalling Windows.

Cheers, Bischa
