Secondary references invisible in some collection lists but not others

[PatHolroyd]

On a correctly displaying page, references for additional taxon occurrences (secondary references) display at the bottom (e.g., https://paleobiodb.org/classic/basicCollectionSearch?collection_no=18140). Other lists do not (https://paleobiodb.org/classic/basicCollectionSearch?collection_no=190942), and I can't see any way for some one who isn't logged into the system as a user to even be able to determine which occurrences are from non-primary references.

This is an odd one. The first link (18140) doesn't list all of the secondary references assigned to the collection (there are 12 secondary_refs). There are only 5 references assigned to individual occurrences and all are listed.

In the second one (190942) there is one secondary reference and one occurrence does have that same reference assigned to it specifically.

This is clearly a Classic reporting bug and will need to be ferreted out at some point.
