By default, only the initial pair indicated by the dropdowns will be created per the text below them. If the checkbox is checked, then a return pair will be created with the regions switched and slightly different arrival conditions.
The buoy's waypoints will need to be set from the Flightgroup tab or Map. If there are additional Arrival conditions they will also need to be set back in the FlightGroup tab.
