Log templates often not working

[Plethodon]

When I create a new template, for example to view logs from a particular interface, I often find that if I switch to the new template that I get no records.  But if I manually enter the same criteria I get plenty of records.

Also, when I recently created a template that had an interface criterion and an address criterion, when I select that template the presented criteria shows something like "iface is lan" and "address is lan".  Uh, that's not even possible. And I get no records. Any idea what's up?

I should have mentioned that this is for Firewall Logs in Liveview.
