As far as i'm aware, you'd need Barcelona main team to get relegated, both teams can't play in the same league.

cant i change it in the editor

if you have the editor you can change the league rules and make that B teams can be promoted. but I don't know how to do it step by step. I think you must use change country rules and then choose the spanish league and then you can untick a case.
