NFA6: Interface Alias/Desc Irregular or Inop

Clicking on the " Configure Device Settings" icon and getting into the " Configure Device Settings" dialog box, I configure the "Default Interface Name" for either "IfAlias" or "IfDesc" but it doesn't matter, it never uses the Alias (configured via the Interface's "description" CLI command.

SNMP is working, it changes some of the interfaces, but not all. It is an irregular puzzle. Switch is a Cat4500/Sup4/12.2(31)SGA1 Enterprise. I have used GetIf and found the descriptions in enterprises.9.2.2.1.1.28.x.

I've never had this problem (or noticed) until just a few days ago. I updated to NFA6 about 3 weeks ago IIRC.
