If I recall, the first FCM command defines the record side, then, if different, the second one defines the source. In my example, with mixed sources, it does not seem to indicate that the second event is drop frame. So something strange going on there either by FCM or by ; or : in the timecode.
You change timecode by clicking in the START field for that clip and entering a new value. Or use of the AuxTC columns to track a different timecode if needed, including DF or NDF.
