Hello.
I was examining the roof from the trunk in both the closed and open positions today, and I noticed that there's a pretty big gap between the rear windshield and the parcel shelf. I also noticed that in the roof down position, the 2 bumpers on the parcel shelf lie against the rooftop in the exact positions where I had the paint wearing from the roof. Now I'm wondering if the shelf needs to be adjusted so it sits up firmly against the windshield. Does anyone know if the shelf is supposed to hang down that low, and if there a way to manually adjust it?
Thanks!

You can easily see the gap here.
