Howdy, 2012 F150 6' 1/2 bed, I was wondering if anyone has this particular cover with the same issue. The rails on the cover arent lying flat along the bedrail, the center section sits higher than the forward and rear sections by about 1/4".....looks like crap. I installed the cover in January and thought it may relax after being on a while and sitting in the sun. Ive contacted Tri Fold and have been given a number to tech support but have had no luck reaching anyone.

Any ideas?
