Get player back from B-Team

Hello,

unfortunetly i punished my player after getting a red card in a game.

I sent him to the b team cause I was really frustrated. The problem now is, that I can‘t get him back?

He is in some sort of a team of auditioners..

All I can do is offer him game time in my u21/u18.

Isn‘t it possible to get him back to the first team? Is this a bug?

Tried literally everything but nothing does work in order to bring him back..

thank you in advance 🙂
