Not normal, but the WD-282FWDC-6 door is reversible by taking the hinges OFF, and then flipping them to the other side. SO there's a real chance that your bottom hinge simply needs to be tightened. You'll need to refer to the door flip instructions in this post:

If one hinge is damaged, replacement parts are available. Note, there are two washers that should be installed on the hinges as well to help with closing.
For what it's worth, the fridge is originally from Way Interglobal - which Lippert acquired - so while you may have to go through Lippert for customer service, you might find some Way Interglobal support when doing searches.
I recommend googling:
"WD-282FWDC-6" and "hinge" and browsing through the result (you'll actually find your original post this way).
Not much, I know, but I hope it helps.
