UCP not answering on the port set in System Admin

I'm running a fresh install of 6.12.65-30. The system is running well, except I cannot successfully change the listening port for UCP. The ports are applied without error, and all services answer on the ports set except UCP. UCP does still answer on port 80 regardless of what I set in System Admin.

I am running System Admin 12.0.45.2.

The contents of schmoozecom.conf are:

Relevant Netstat output:

I am at a loss... Any suggestions would be greatly appreciated!
