My only guess is they somehow got deformed when they were off the truck. They're pretty thin and easy to bend, but fit snugly around the headlamp so they should conform to the round shape when installed. You say they hold the lamps in place..... I guess I don't see a problem. If they're bad enough to bother you, junkyards should have lots of them. Or buy new ones, many vendors sell them.
