Those things get bent to hell the first time they go into anything. That one hasn't been used, unless it goes into something EXTREMELY too large for it. Probably a factory worker dropped it and it was faster and cheaper to grab another one than spending the time to look for it. Also a possibility it's not even from the jeep lol. Most shutters get installed into siding using those, so it could be random.
Edit - and if appropriately sized, they are a pain to get out and have a bunch of pry marks on them.
