Pop goes the weasel. No, wait that was my hood.

Today, for the second time, my hood popped after hitting a bump on the highway. I've cleaned and lubed the springs and catch, and I'm at a loss as to why this keeps happening, since it seems to close and latch, though the passenger side doesn't seem to go all the way down (small gap). When I close it, even a forceful pull on the hood doesn't budge it, but a highway pump pops it... any clues?
