Hi All - Thanks for responding. You are all correct. I didn't fully pull the piece off, but I pulled the corners and top off and was able to get the left side seated back correctly. Unfortunately, the right side appears to be broken -- I can see a severed piece of a plastic "tooth" (hat tip to AdamSheikh). My hunch is it was broken by the company that installed the window tint. The piece looks better than it did, but I'll search/source a replacement piece of plastic.
Quick update. VW fixed this when I took the car in for it's first [included in deal] oil change. They just replaced a plastic clip that had broken. No charge.
