The Thule Stravan sleeve scratches and dents the 13" MacBook Pro Retina Display

The Thule Stravan sleeve scratches and dents the 13" MacBook Pro Retina Display. The Thule Stravan sleeve has a metal (steel) zipper which scratches and dents the Laptop. The outer aluminum edge profile of the MacBook Pro Retina is narrower which allows contact with the zipper. It is obvious Thule did not test this case out well with this computer. In the reviews another individual has stated the same problem, I wonder if this problem exist for other MacBook Pro 13" Retina users?
