As other have said, this is an easy fix if it really bothers you.
Wolfgangs pic shows a modified CMC inner bracket (it was modified to clear a sway bay) but otherwise that's what the CMC will look like. The VS brackets should look very similar as most of it is identical to CMC's, but with better execution in the build.
There's also some advice in the CMC build manual (available here on this site to premium members only). I've seen real "P" cars where there is no gap at all and the bumpers are fitted tight to the body, and others with a bit of a space?
The grommets are standard VW issues as noted also available in many locations.
I'd guess (2) 3/8 or 5/16 bolts on each bumper bracket would attach it to the brackets in Wolfgangs photo. Disconnet those and slide the bumper off. Mark it and move the existing holes and inch or so and use an oversize drill for adjustment.
Or just drive it as is and enjoy it.
