HB Set Zones - 'invalid zones served by different HVAC systems' HB Model Validation error

Hi there,

I am having some trouble with the HB Set Zones component and generating a valid honeybee model.

I seem to get the following error when applying ideal air loads to zoned rooms.

Validating Model using honeybee-core==1.61.29 and honeybee-schema==1.59.0
Model checks completed.
Your Model is invalid for the following reasons:
Attributes for energy are invalid.
The model has the following invalid zones served by different HVAC systems:
Office - [HVACS: L00_Office_e2b76c6d Ideal Loads Air System, L00_Lab_75d8964f Ideal Loads Air System]
Lab - [HVACS: L01_Office_db55a925 Ideal Loads Air System, L02_Office_fc515a19 Ideal Loads Air System, L01_Lab_dcd74f98 Ideal Loads Air System, L02_Lab_aa929d55 Ideal Loads Air System]

I have tried applying ideal air using Ironbug detailed HVAC, but get the same issue.

Please see gh file below for the simple model set up and 3 different ideal air assignments I have tried.

Any help on this would be much appreciated.
Thanks,
James.
