I have several gpx files of different routes that I want to join and then import to an route planner programm.
So far I have importet the gpx files to QGIS. After that I have converted them into shapefiles and then merged these shapefiles into one singel shapefile. Then I saved it as a gpx file.
The problem now is that if I import the gpx file to the route planner programm, it only importes one of the inital routes and not the whole joined route.
What did I do wrong?
