If you have a different version of the card on your team you will need to take him out. It’s a pretty weird glitch but I bought the 99 Darvish card and thought I lost it. I just had to replace my Gold Darvish with any other card, then when I went to replace again both were there. It’s happened with several cards now that I have multiples of.
You may have a lower different version of Acuna on your team or you are playing a mode which doesn’t allow WBC players.
