[Mailman-Users] Held messages not appearing on administrative web page

I have a number (about 500) of old held messages in /var/lib/mailman/data that should show up on the administrative interface of the list's website, but don't.

2 questions:

1. what determines if a file in /var/lib/mailman/data shows up in the web interface?
2. How can one reindex or rebuild the contents of /var/lib/mailman/data so the missing data shows up?

We are running Mailman 2.1.9 on Linux SLES 10.2.

Thanks!

Anne
