Zone Sizing Data with Ideal Loads

I want to quickly output zone-by-zone heating and cooling loads in the HVACSizingSummaryoutput report. The simplest approach I know is to use an HVACTemplate:Zone:IdealLoadsAirSystemobject. Though I can't seem to get my model to output the Zone:Sizing object like the other templates. For example when I replace the ideal loads air system and useHVACTemplate:Zone:VAVon the same exact model Zone:Sizing is created as it should.

I do have "do zone sizing calculation" selected in SimulationControl, and when I manually add Zone:Sizing, my simulation runs and the HVACSizingSummaryoutput report is populated. I just want to understand why the template isn't doing this like it should.

Here is a snapshot of my idf:

and the expanded idf (no zone:sizing object):

I can see that the zone:sizing object should show up in the expanded idf, as it does in the example file HVACTemplate-5ZonePurcAir, but it does not in my file.

Though I can't seem to get my model to output the Zone:Sizing object like the other templates. For templates, for example when I replace the ideal loads air system and useHVACTemplate:Zone:VAVon the same exact model Zone:Sizing is created as it should..

I do have "do zone sizing calculation" selected in SimulationControl.

I want to quickly output zone-by-zone heating and cooling loads in the HVACSizingSummaryoutput report. The simplest approach I know is to use an HVACTemplate:Zone:IdealLoadsAirSystemobject. Though from what I can't seem to get my model to output the can tell, it does not create a Zone:Sizing object like the other templates, for example HVACTemplate:Zone:VAV.

I have the "do My question is : why is this? Is there another way to get zone sizing calculation" selected.

Here data from an ideal loads system or is a snapshot of my idf:

I can see it correct that the zone:sizing object should show up in the expanded idf, as it does in the example file HVACTemplate-5ZonePurcAir, but it does not in my file.this template requires you to add sizing objects separately?

Though from what I can tell, it does not create a Zone:Sizing object like the other templates, for example HVACTemplate:Zone:VAV.

My question is : why is this? Is there another way to get zone sizing data from an ideal loads system Am I missing something or is it correct that this template requires you to add sizing objects separately?
