Did the documents that are no longer presented go through a different workflow than the ones that are presented? For example, maybe one set was entered through the regular submission process, and the other set was created using the QuickSubmit plugin.

No. They were all submitted and uploaded at the same time. And all pdf buttons were all showing as present until the upgrade from 3.02 to the current version.
