Phantom rules remain after interface deletion

[jason0]

Hello,

I am planning to upgrade from 2.1.5 to the latest release.  In the process I have been significantly reducing my network's complexity here: I removed three vlans, openvpn, ipsec, etc.

I can't delete an alias though: I get the error "cannot delete alias.  currently in use by 'block openvpn from logicbox'"

I backed up my configuration and discovered the rule in question (and others) are still defined in the downloaded configuration.

Aside from rebuilding the entire pfsense router from scratch, or rebuilding the interfaces and deleting the rules, how do I go about stripping out the cruft?

Thank you for your time!

Edit the downloaded config and restore it to the unit?
