This would happen if you had the fan in anything except 'Auto'. The A/C fan is 120 volts so it wouldn't run until you have 120 volts to it (generator running).
As for losing the settings, make sure that the last thing you do after programming both zones (you have to scroll through both, even if you don't want to program zone 2) is press the program button again. So, at minimum you'll have to press the program button three(3) times to get it to hold.
Is this the manual you have? CCC2 Thermostat Manual
P.S. If this doesn't work, you can try initializing the thermostat and reprogramming it. The procedure for that is on page 11 of the manual I linked to.
