Bug description

Maps shows a simple gpx track (one created by me) but will not show a track exported from Basecamp in gpx form. However 'scan-tracks' does 'add' these Garmin tracks (they just don't show up under 'tracks' on the map).
Attached is a sample Basecamp track (gpx) converted to .txt because gpx not supported
The Kepler Track.txt

Steps to reproduce

1. Run scan-tracks - shows all tracks 'added'
2. One Track shows up but others don't

Expected behavior

All tracks should appear on map

Start with the scan-tracks entry point and reproduce the issue using the attached The Kepler Track.txt Basecamp export, comparing it with a track that appears on the map. Trace why the Basecamp tracks are reported as added but are not displayed; done means all valid tracks from the sample file appear on the map.
