Something’s odd at Ath.Bilbao. Check out their latest match report. There are 2 players that appear twice on their formation, Cervantes and Palacios. They both appear as D and A, even though if you check the squad there’s only one Cervantes and only one Palacios.
Cheers.
I’ve just figured out what is going on. Yes, it is a bug :-(
Fixed.
