Vinyl top and drip rail trim

When I removed the remnants of my original vinyl top, the vinyl wrapped around the rail and underneath where the door window seal trim is. I installed my new vinyl the same way but now am having trouble getting the drip rail stainless to lay flat on the underside.

I’ve seen some posts here saying their vinyl was factory cut before it goes around the corner. I wonder why I found mine wrapped under and other folks are saying it stopped just before going under?

You can see it wrapped around at the left where the hockey stick trim goes.
