Yes, the zipper pull mark is pretty inevitable. The felt flap protector should be used when your bag is not being used.Those marks are most likely from the zipper pull from the pocket on the underside of the outer flap. It rubs against the inner flap and makes those marks. It's pretty much inevitable over time and with normal use. Be sure to use your flap protector when the bag isn't in use as it will cut down on the rubbing.
