I have managed to create routes that have one or none waypoint.I do not think it is correct.
Example to create with 1WPT:
You can click on PLUS and create new route from the map and after creating first point just click somewhere outside map or put escape button. The result is route with no name and 1 waypoint.
Example to create with no WPT:
Go to Voyage plan from the menu. Add route button. Enter coordinates tabstrip. Leave = Escape or close the window.
Please can you help repairing the behaviour? Thank you.
