That rib on the stock steel fenders does the same thing. If the edge of the FG was rounded a bit more like the steel fenders it wouldn't be as noticeable. I'd rather have it do that than try and make it flush. If the rib was flush with the tub then the fender above it would be in-set from the edge of the tub by that amount and would look far worse. Since it's a one pc you don't have much choice anyway as you can't adjust the pieces independent of each other.
