TL;DR: The fact that you have a discrepancy in your results between OS 1.14.0 and 2.2.0 is not coming from this. You can safely ignore these new fields.
I'm not sure why you actually see the splitter/mixer names in the OS App now (I don't see any reason to, you shouldn't be able to change them... but might be missing something), and the return air schedule either since it's not even implemented.
Demand Mixer Name and Demand Splitter Name show you the name of the demand mixer/splitter:
In the above image, Demand Splitter B and Supply Splitter are showing you bogus stuff, they're actually empty, the method returns boost::none. It's showing you the name of the airLoopHVAC for some reason...
Supply Splitter Name and Demand Splitter B only apply if you have a Dual Duct airLoopHVAC. Looking at the source code, A is the hot air, B is the cold air.
ReturnAirBypassFlowTemperatureSchedule isn't even implemented in OpenStudio at the moment. See source code
