I think I got it. The older version of the software (vB 3.5) was cookie based - but once you've logged in - then either your session is timed out or you log out, everything is considered read.

Inactivity/Cookie Based - once a user has been inactive for a certain amount of time (the value of the session timeout option) all threads and forums are considered read. Individual threads are marked as read within a session via cookies.

Now I've switched it to a database option. It should work now.
