@Keigo, when I run 5ZoneNightVent3 in the latest V26.2 I see OA and system air flow. I didn't check all nodes in the air loop and zones but it does appear to me that the system activates for Night Ventilation.

UPDATE: I added zone nodes to the investigation. Sure enough the zone side of the system has 0 flow during NightVentilation. This is because the TU is using the fan schedule when it should be Always ON.
