Freezer drawer hinge won't engage

I came home from vacation and went to open the freezer drawer door and it came off on the left side! it seems like the hinge that holds it in place vertically won’t engage, but the tilt hinge seems to be working fine. Any suggestions on how to fix this - am I missing something obvious?

Here’s a picture if it helps…

You will find info on this in the owners manual.

Actually, the manual only discusses removing the lower drawer by detaching the rails the drawer slides on, it oddly has nothing about the hinges. Do you suggest I remove the door completely and try to reconnect it that way?

You will need to study it to see how it goes on, most times the manual will not help that much.

How do you fix this hinge.
