Having trouble with UKS and USI-LS

[Swartz55]

So I've been spending a lot of time trying to figure out how to make a base with UKS, specifically the MKS parts. The part that confuses me is that whenever I activate agricultural modules, start habitation in the modules or do anything like that, the total "days" left for my Kerbals to live doesn't change. Ever. I tried reinstalling both UKS and USI-LS, but that didn't help. Am I just horrible at figuring out this mod, or might there be another problem? Thanks!

Did you forget to bring aeroponics modules?

No, I loaded it in career and put all the necessary parts together. Adding the parts seemed to change the total days, but turning them on didn't.

Could someone maybe make a working craft and then just upload the part file? I switched to TAC Life Support yesterday, but haven't had time to see if the days will change when I activate the modules or anything. I'd really appreciate it.
