G1 Metroplex help

I never owned one before until now.
I am having....intermittent...trouble keeping his ramp door closed.
Is there something special I'm supposed to be doing to keeping that bay door closed and I'm just fluking into getting it done right once in a while, or is it something else?

Thanks.

There is a point where it kind of tightens up and stays in place, if I remember correctly. It’s been a while since I opened up his ramp on my copy.
