Openfire 3.8.1 & Monitoring 1.3.1-beta2 not Archiving

I am currently running Openfire 3.8.1 with an external MySQL database on a second server.  We recently upgraded the Monitoring Plugin from 1.1.1 to 1.3.2-beta1.

Since the upgrade no messages are appearing under Archiving.  The archived conversation count keeps increasing however the archived message count has not.  I have tried downgrading to 1.3.1-beta2 and restarting the service with no change.

Any help would be greatly appreciated.
