I've had Serafin, Maia and Pallegina in my roster while I leveled up other companions. I have four companions at level 8, and the three I just listed are at five. I can't equip Serafin Maia or Pallegina from my roster. The game lets me select a lower level companion to put into my party, and once I hit accept they get put back into my roster. My three other level 8 companions I have selected stay in the party. I'm unable to play Pallegina, Serafin, and Maia at the moment because of this. I was able to recruit a level 1 adventurer and he's able to be a part of the party, so I don't think It's a matter of leveling. Very confused
