KPA500 Operate/Standby auto drive power change quit working...

ke9uw
I updated the KPA500 to 1.54 and went to o=Operate on the amp.
The K3 displayed "Operate", but the K3 did not change the power to low drive power. I do doubt if it had anything to do with the update.
Then I tried to set the power levels switching from Standby to Operate and back. Still no joy.
Then I restored the K3 to an earlier configuration and all is well. Now the power switches from low power on Operate to high power on Standby.
Is there some menu setting that can select whether that works or not?
I could not find one.
What could have happened to the K3 to keep that from working as advertised?

I believe PWR SET in the CONFIG menu has to be set to 'Per band' for it
to save two power settings - one for barefoot, and one for amp
operation.  It is on page 53 of the K3 Owners Manual.
