Bluebeam Sets won't print the latest revision

I have a .bex file (aka Bluebeam Sets) that I had been able to print the latest revisions just fine… until recently.

Now, when anyone on the team goes to print the latest revisions, the Print diolog seems to list all the pages for each combined PDF, and only print the first chunk of pages.
(The example below shows eight combined sets, but the total number of sheets printed at the bottom shows only the number from the first: 1-575).

What am I missing?
