Cover doesn't seal

The orange cover on my Form 1+ does not seal along the bottom. There is a 1 - 2 mm gap between the base and the gasket all the way around the cover. Is this normal? Will it allow light to get in and cause the resin to slowly cure? The cover registers as closed when it is in this position and I can print.

Mine was similar. If you loosen the socket head screws on the hinge a bit, then gently adjust the cover to fit flat, then retighten the screws, all will be fine.
