Mine was the same I had to sand to get rid of rubbing, also the flap gap seal requires some attention. I got lucky it will hang up when you have them down and then go up, I had one that would go up. Luckily someone mentioned the issue that same day and I just the flaps back down and after that made it were the travel didnt go past the plastic gap cover.. another fix is to heat them up and roll them a bit more.
