Why is only my bathroom properly heated?

edit

I'm making a test building for graduation project and while playing with openstudio I got a ground source heat pump setup. And after alot of trial and error I got the heating in my bathroom to work but the other rooms don't and the settings for the HVAC are almost identical. Can anyone look into my OSM file to see whats wrong? https://drive.google.com/file/d/13POn...
