Hey there,
We have the same intermittent noise. I have not had a chance to figure it out properly as yet. There is a piece that seems to be causing the noise, but it has to be able to move to seat everything when in the closed position, so haven't tried to stop it from doing that yet. It hasn't gotten too bad yet - but probably something I will need to look at properly soon.
Sorry I can't help... other than to commiserate...
Let me know if it's the same or if you figure it out!
Good luck!
