So there are multiple copies of fake players in the team rosters AND free agency? I've never seen that, unless you're now talking about two different things. I can't help the fake players the game generates in FA and I have no idea why they did that. But, you can reset rosters which should get rid of them and then save this reset roster to whatever you want (but only the game will recognize it). You're going to have to clarify what you mean, though.
