DesignSpecification:ZoneAirDistribution

I am stymied. My auto-sized system is coming out grossly undersized (which is strange, since it almost always comes out oversized). I know this topic has been covered here.

Both the Component Load Summaries (AirLoop and Zone) agree. But then, System Sizing is showing half of what is required. Plus, why does this show mixed air at 32°F for cooling on summer design day?

Please, can anyone help?: image description

The output variables for the sizing runs even show the system is using significantly more cooling than what the System Sizing Information is reporting: image description

The Zone Component Load Summary and Airloop Component Load Summary appear to agree on the correct value.
