GAC Error, Able to use Teams set on defence on Offence too.

Strange bug never happened to me before. My GLO, Jabba and Rey plus a few other teams and all placed on Defence for GAC, However i’m able to also use them on offence as-well. I’m refusing to use them as it’s a clear cut Bug and don’t want to get banned. Not sure if my opponent has the same problem too. I’ve attached two photos, One of my defence and one of my units available for attack and yeah I can use both of them. This creates a MASSIVE and unfair advantage. I had attacked with the teams I normally would for offence and only noticed it slightly later on when I could place Rey down for attack.
