Wheel Well insert trim missing?

[esunday]

My wheel wells on both side seem to be missing the INSERT TRIM to cover the screws that fasten this to the tt. It was never there.
Is it normally not put in on the wheel wells? Just noticed it as I was doing some work. Seems like it would help keep the rain/water/mud from seeping through the screw holes.
Should I worry about this?

Anyone familiar with this? Thanks!

I've never seen any trim there, it would actually trap water.

No trim in mine.
