Default OBDII failed self test smog test failed

97 SC2 210,000 miles mostly original equipment.
I just failed a California Smog test. It passed all emission requirements with flying colors, however it failed the OBD self test. I ran codes and here are the results.

Misfire monitor - ok
Fuel System mon - ok
Comp component - ok
Catalyst Mon - inc
Htd catalyst - n/a
Evap System mon - n/a
Sec Air System n/a
A/C Refrig Mon - n/a
Oxygen Sens Mon - inc
Oxygen Sens Htr - inc
EGR System mon - inc

The car runs as good as ever. 31 mpg. I changed the ECTS sensor and I cleaned the EGR Valve today. Still, same results. No other codes are indicated. I haven't had the battery disconnected in months. Any ideas?
