Data import does not create a route

Hello, I am stuck and need assistance please. I plan routes with kurviger.de and export both route and waypoints by creating a link. I import this link into Umap (Dataformat = GPX new level), but only get the waypoints and the route appears as distance as the crow flies.
What am I doing wrong? Thanks

Youn need to export/import the track.

(Umap does not have a routing system. So it does not know what to do with your waypoints and will just connect start and end with a line)

Thanks a lot. you have bee right absolutely and my problem is solved.
