Won’t let InstaPot seal

This thing would be great but it has to sit just right to be straight. But even with it just right my pot won’t seal. Steam leaks out the side and I’ve tried and tried and made sure everything else is clean and correct but every time I end up taking my food out of the steamer and putting it back in and then it seals right away. If they made it a little narrower and a little shorter so it sat inside instead of flush with the edge it’d be great.
