the center glass panel OE gasket has flaps (similar to what you see around the rear glass by the trunk) and can be peeled back and easily kinked by the aftermarket loop.
Given the tension at the corners and even along the doors, its possible that the aftermarket insert will eventually eat away at the seals deep below the glass edges, but initially, having them kinked like this does nothing.
Either remove or re-seat around the corners so the insert doesnt kink in like in the photos. It can be done, installed the thicker silicone inserts on two model 3s and neither of them cut in/kink like that after a year on the cars... initially they had a tendency to, just needed a re-seat.
Ideally the sellers should either redesign the corners to have wider glass corner mating flaps or some sort of rounded 90 deg corner guides to prevent this. Plenty of room for that.
