What, they are showing up in the war room?
It's unfortunately a bit more tangled to remove them from the roster during early FA, there's a lot of logic that makes that work that would all need to be removed and tested before rolling it out. It's not been a high priority because you currently have a filter to see just players who are under contract during that time, I've been focusing on more pressing issues.
But players on your team should not be showing up in the war room, if that's happening this is the first I've heard it.
