Bent bumper bracket?

looks like it was bent in (causing the crease) and them pulled out/straightened to spec. pound it out or just run it if it holds the bumper straight. probably an easy find online.
You could probably bend those out with a 18" crescent wrench while its on the car. Just adjust them down to the 14g or whatever it is, grab it and bend (toward the adjuster). Thats the only thing I use that wrench for besides the house drain cleanouts.
