I apologize, but I'm having a tough time following your post. Gennie is pushing either 120v or 240AC. The batteries are all 12v or 24v DC.
When you started the Gennie, which 'leg' didn't come up? AC or DC?
I would expect multiple AC leg's, but only 1 DC leg. Start and Gennie Batteries would be isolated from the house bank. If gennie and engine batteries are showing good voltage and cranking, then this sounds like it is the house battery system only.
There should only be a main bank shutoff, then a main breaker on the 12v panel.
It is possible that you drew down the house bank? 14.1 on the generator would tell me that it is being fed a charge either by an alternator or battery charger.
12.5 would tell me that that bank is NOT getting a charge and is around 50+% state of charge.
