Also, I didn't see a <dc:subject>Catalog tag in your OPF. Is the Catalog file that you're working with a cleanly generated file (which would have a Catalog tag), or one that you re-converted? Better to start with a clean catalog file.
Unfortunately, that was a clean, not re-converted Catalog. The "subject>Catalog tag" was "conspicuously absent" in my OPF.
Your OPF compared to mine showed several differences.
I'm guessing that my custom columns "#author_ln" and "#title_ln" must be causing some problem.
Will be out of town for a 3-day weekend. Will remove the custom columns next week and see if that fixes things. More next week ...
