Erroneous display of gpx-tracks

[karow36]

Describe the bug

gpx-tracks generated from openstreetmap - relations using https://cycling.waymarkedtrails.org/ are displayed wrongly.
There are connections (straight lines) displayed between points that are not connected.

What have you done to circle down the problem?

I checked several gpx-tracks
I checked the display on other Apps / devices (Android-App osmand~ / Device GPSMap64)
I checked the list of open bugs

To Reproduce

1. Go to https://cycling.waymarkedtrails.org/
2. Click on the search bar, insert 10885589 --> you will get the relation Teufelstour.
3. Create the gpx-track-file Teufelstour.gpx for this relation 10885589 by clicking on GPX
4. Open the file with qmapshak.
5. Display the track on the map.
6. See the error (see screenshot below)

Expected behavior

Display of the track without the erroneous connections between not connected points.
