Your rails are mounted too far forward. That rubber block must have a 1/8-1/4 gap so it doesnt rub against the top fabric. If you leave it like that, you will eventually wear through the fabric. This should solve some of your wrinkling issue too. I would also check the aluminum bow right behind the glass. moving the rails back a bit will help, but you may have to adjust the bow also so the top edge of the glass doesn't deform the fabric so much.
