Please help.

Configuration : dji mini 4 pro, RC2 , Mac , iphone

I create new mission on iphone. Export the kmz file. Send it to my mac. Change the dummy waypoint. Fly my mini 4 with the waypoint. All well, but only for once. At the end of the flight the flight paths are disrupted.

The screenshots

Sorry for my english, write from germany. Hope you can support me. I use this waypoint every week. 

Thanks
