Ending was kind of frustarting for me, didn’t explain much. I guess they want to leave everything for season 2

I’ve seen some discussions on the show and everyone obviously talks about the ending, but I’m still wondering why the displays in the bunker, before they turned the power off to fix the generator (which somehow doesn’t need the steam to go through the turbines either), showed the fake projection of a healthy outside world. I get it that they use their magic space tech to show that within the visor of the helmets, but why would it even be part of the displays at all? And why the hell did no one react to it? We saw that people saw it, including that cop lady, but absolutely no one even mentions it after it happened throughout the whole season.
