2021 Bambi - Spare Tire Carrier - missing bolt/pin ?

[Librarian]

Question re spare tire carrier under our brand new 2021 Bambi - we noted the spare tire/holder was sitting low before towing out - crawled underneath to find the back of the tire carrier had no bolt or pin to hold it up to the frame. There was a hole in the carrier and AS frame, so we put in a basic hitch pin in it and that seemed to work as a temporary measure. The question is, what sort of fastening device should it have/what may be missing? Photos of spare tire assembly appreciated..... Thanks.
