I ran into that kind of issue when I played with the Level 1 at some point. I was using alias only.
It looked like the table were locked by Firewall Rules, when I disabled pfblocker, the table would still showed up.
I removed pfBlocker and the table were still there under Diagnostics: Tables!!!
I install pfblocker and at some point I recovered. But I am not using Level 1 at this time.
