Does the latch inset into the door have adjustment bolts? can you verify that as the door closes, the latch is causing it to slide upward?

One way to see where it is hitting is to paint the striker bolt with white-out or a similar substance. Then slowley close the door until it makes contact (but not shut) Do this to see where on the striker bolt the latch is hitting. It should be in the middle, not at the bottom.
