Manual commercial update only update default stationID

Hello, I’m running mAirlist Professional 6.3.1 build 4335. I have two stations configured. Commercials are scheduled with an external software and imported in mAirlist. That works without an issue.
When generating playlist for both stations, the commercialschedule of both stations are imported correctly.

When performing a manual update of the commercialschedule, only the schedule of the default stationID is imported. Even, after selecting the other station via Menu - Station.
Meaning: station1 is default StationID configured in database. manual update for station1 is ok, manual update for station2 is not ok: schedule of station1 is imported.
Workaround is changing the defaultID in database. But it would be nice to have it working, just by selecting the station in the databaseapp.
