Here is what I have learned today.

If you look carefully at the gasket, it has a center section that can be removed. The center section acts like a wedge to tighten up the gasket.

The fix is you remove the wedge, called a windshield locking strip, move the gasket back to it's original position, and reinstall the wedge. However, it supposedly takes a specialized tool called a windshield locking strip tool (gee that's brilliant on my part) to put the wedge back in easily. Found one on Amazon for 10 bucks. I'll let you know how it works out.
