THey aren't real players, so it's just made up just for the team, because all the German IRL internationals are still there, i.e Lahm, Gomez, Muller at Bayern, so they don't add the internationals on the game instead of the others, so they are only there for international games
Thats what I think
Yeah it's not that.
It's something to do with the rights of the national teams, and administrator will be able to say exactly why.
There is a fix, search on google for the problem and it will direct you to the thread on fm base. If you use steam you have to delete 3 files from that update and also the SI folder update. Then start a new game and it will be the correct players.
The thread tells you where and what files to delete I have done it but can't remember.
