Ventilation component bug

Hi guys
The Ventilation component does not work if AirChanges/Hour is used.
I tested it and it only works when used with Flow/ExteriorArea.
Please find attached my file for verification.

Good afternoon!
I forgot to add the image of the bug.
I’d really like to know how I can fix this problem without scripting it.
Best regards.
