Title: Players permanently locked after completing Gauntlet Mode event

I have multiple player cards (Sane 124 OVR, Cunha 124 OVR, Musiala 124 OVR, and Rooney) permanently locked as "in use".

They were used in a Gauntlet Mode event that I completed, which then disappeared from the menu upon completion. Because the mode is no longer accessible, I cannot remove these players from that lineup, leaving them permanently locked and untradeable.
