Description
I'm attempting to run a two-stage air conditioner with gas furnace using the Coil:Cooling:DX:VariableSpeed and AirLoopHVAC:UnitaryHeatCool objects. However, the model appears to be using the speed 2 air flow rate when operating in speed 1. I ran this using a recent develop build.
IDF, output file, and other associated files are here:

The Excel output file highlights the rows and columns that exhibit the issue. From 14:10 to 17:10, the load varies from approximately speed 1 capacity to full load; however the coil air mass flow rate is constant. I believe the air flow rate should vary under these circumstances. This impacts the fan power and coil SHR.
