It looks like you are confusing Case tabs with Design tabs. Designs are intended to have different building features/components but share the same building geometry, location, utility rates, etc., whereas Cases can differ in any of these ways. So if you are looking to compare different sets of features for the same building geometry/location, then you generally want to use Designs.
In the sample file, there are four case tabs, and two of these cases are in Design mode. Each of those cases in Design mode will have an additional set of design tabs on the Options input screen. So the "what-ifs" Case has six designs ("base", "walls", etc.). Those six designs are shown on the output screen.
In your file, there are three case tabs. Assuming they all have the same geometry and location, it sounds like you wanted them to be three designs within a single case. Then you would get an output with three results.
There is more description in the help file.
