The second mission didn't start from the first waypoint

I uploaded the first mission with 14 waypoints. Everything went as it should. Then I switched from AUTO mode to FBWB mode and uploaded the second mission with 13 waypoints. When I switched to AUTO mode the plane didn’t start from 1 waypoint but from 12. Do I have to restart the sequence somehow?

You can restart mission via MP buttons “restart mission” or manually set # wp

In AUTO mode Plane will follow a mission (a set of GPS waypoints and other commands) set by your ground station. When re-entering AUTO mode Plane will continue from whatever mission item it was last doing, unless you have reset the mission. If the mission ends with an item that does not continue indefinitely (like LOITER UNLIMITED), an RTL will be executed.

Great, thank you very much.
