Tournament sets teamcaptain of a inactive account

I have a big problem.
I want to enter a 1v1 tournament. Well i create a team and well… the team is created without me but with a teamcaptain which no longer plays. So in the team info it says; “TEAM CAPTAIN HAS TO BE LOGGED IN THE GAME CLIENT AT THE MOMENT OF REGISTRATION ENDING AND TOURNAMENT BRACKET GENERATION!” or something like this. If i delete this team and try to create a new one.

I dont know why and how but somehow this old inactive account is connected to me in someway as a team captain. But idk where and how. I am not even in a “Kampfgruppe” or sth clan related. Heck i create the team but some other person is the Teamleader? What can i do?

Found the failure… everything is right :D
