Seatbelt doesn't always retract

Wondering if anyone has already had and solved this problem with the D/S seat belt staying in the rear position. It started to take a few seconds to start to move and the time keeps getting longer. Once it starts moving, it goes fine.

Thanks

Is it just sticking? Mine sticks sometimes and when it does I just give it a little outward push to help it get out of the locked position.
