Your model looks good. "Sub Surface 2" and "Sub Surface 3" do in fact represent the same exact surface in real life, but just viewed from the perspective of two different spaces (and for your case ideally different zones). Look at the last column on your screenshot for Outside Boundary Condition Object, they refer to each other. This is also true for interior base surfaces. If you have an interior floor of one zone and look at its construction. It should be a mirror of the construction of the ceiling of the space below it, because they represent the exact same surface.
This is a bit different from how models like gbXML work where there is just one surface in the model and it refers to multiple spaces.
As far as the lack of solar gain, make sure under simulation settings for "Solar Distribution" you set it to "FullInteriorAndExterior" vs. just "FullExterior" which is the default. Keep in mind while light and solar gain can go through interior windows, it is diffuse, so it may not hit the floor of the red zone like you expect it will. It may spread more across all surfaces.
