I downloaded several gpx tracks from www.cirkwi.com and tried to import them to Garmin Connect Web. No technical problems on importing but only a very small (the first) part of the tracks is shown on the map. Other applications (for example Osmand) showed the complete tracks on the map.
I opened one of the .gpx files in a text editor and found out that multiple track segments '<trkseg> ......... </trkseg>' seem to be the problem in Garmin Connect. After removing all <trkseg> and </trkseg> from the text except for the very first <trkseg> and the very last </trkseg> in the file, saving as .gpx and importing this newly created .gpx file to Garmin Connect, the complete track is shown on the map.
Is there a way to show the complete track on the map in Garmin Connect without having to edit the .gpx file?
