As you can see, there is a black plastic piece that moves up and down by turning the two nuts on the bottom. The black plastic piece has two tabs that matches the two openings on the bumper.



If you tighten it too much, you won't be able to snap the bumper in and will just tear up the bumper tabs. Tighten it just enough to push in the side of the bumper with some resistance and snap into place.
