Ok, I think I can confirm that the first issue is somewhere between a mistake, and the user interface allowing me to do something dangerous. (Sorry Linus for the wild goose chase.
I multi-selected all of my dives for the trip, and chanced the "type" of cylinder 1 to a 3l cylinder, and saved it. This seems to have updated the o2% and He%, though not the pressures, for cylinder one on all of those dives. I wouldn't have expected that to happen. However, I'm still stuck with cylinder 2 now being a hybrid of my oxygen pressure and first gas switch cylinder.
