Outdoor airflow rates - Honeybee to Ironbug

Hi, quick question. I am currently using a workflow which assigns Ironbug HVAC system to honeybee room objects. I’m getting some weird outdoor airflow rates for the VRF +DOAS system (some systems with no outdoor air assigned to the honeybee room program are showing outdoor air). How are honeybee ventilation parameters assigned to room programs applied to Ironbug HVAC systems.

If I auto-size outdoor a DOAS system or Zone Energy Recovery Ventilator what values will be used to size the OA flow rate? Will the Ashrae 62.1 values I applied to the honeybee program be the basis for these calculations or something else?
