Welcome to the world of TensionZip pockets. The design makes for expandability of the entry upon unzipping, promotes easier single-handed zipping/unzipping, and is not meant to zip up fully in the traditional sense.
In NJ and seem to be dealing with a similar issue (also ordered J105). You should receive a call from UPS to collect your TIN or SSN so they can submit for clearance. It sounds sketch, but I think it's the only way to get it moving.
