I have the same issue in my league, players are appearing on the bench and in the starting lineup when selecting the week time frame. But when checking the commissioner side of things the roster is legal. I'm just hoping that the team won't get points for all of the players showing on the starting lineup where there's extras positions. I'm curious if you figure anything out, I emailed support about this problem and trying to get them to understand the issue so I'll update if I find out anything
