Help me understand workers and work places

[KiloJKilo 1]

I currently have a low wealth worker population of 80 and a 80 total jobs with none available and no unemployment as you can see in the below screenshot. If I look at individual buildings however, there are spots open in the low wealth tier. It's like this in all of the buildings that have workers. How do I have no unfilled jobs? What am I not understanding about jobs to sims?

Many buildings have a day shift and a night shift. The Wind power plant should have 10 low wealth jobs and 3 medium wealth jobs per shift. So it should either say 10/3/0 or 20/6/0.

 

You'll notice commercial buildings that close at night only provide half the number of total jobs that the 20/7 commercial buildings provide. Add all of them up and you'll get to 80 total low wealth jobs.

 

I haven't really checked Guillaume's mod enough to see what's wrong here.
