Issue overview

This may be and EnergyPlus issue...

When the model is run, the following error appears in the eplusout.err file:
** Severe ** ManageSizing: Requested System Sizing but did not request Zone Sizing.
HEP-24-03 CALCS_002.txt

** ~~~ ** System Sizing cannot be done without Zone Sizing
** Fatal ** Program terminates for preceding conditions.

Current Behavior

OpenStudio does request Zone sizing:

OS:SimulationControl,
{3761ef35-bae8-4829-aabb-a11ecfac8e0e}, !- Handle
Yes, !- Do Zone Sizing Calculation
Yes, !- Do System Sizing Calculation
Yes, !- Do Plant Sizing Calculation
Yes, !- Run Simulation for Sizing Periods
Yes, !- Run Simulation for Weather File Run Periods
, !- Loads Convergence Tolerance Value {W}
, !- Temperature Convergence Tolerance Value {deltaC}
, !- Solar Distribution
, !- Maximum Number of Warmup Days
, !- Minimum Number of Warmup Days
Yes; !- Do HVAC Sizing Simulation for Sizing Periods

The in.idf file also does Request Zone sizing:

SimulationControl,
Yes, !- Do Zone Sizing Calculation
Yes, !- Do System Sizing Calculation
Yes, !- Do Plant Sizing Calculation
Yes, !- Run Simulation for Sizing Periods
Yes, !- Run Simulation for Weather File Run Periods
Yes, !- Do HVAC Sizing Simulation for Sizing Periods
; !- Maximum Number of HVAC Sizing Simulation Passes

Expected Behavior

Steps to Reproduce

OSM file is attached. Click run.
