Getting bottom half of door to lock into hinge

When I setup lately I am having a heck of a time getting the bottom half door post to lock into the camper. Seems like the post on the door is too tall to fit where it is supposed to go. I have to mess quite a bit with the sissor jacks. Also to get the door to latch when I close it I have to mess with it quite a bit. Is this normal? Is something out of alignment?
