All imported tracks come with the same name...

I have imported a gpx file with several tracks and waypoints  from an exported/saved BaseCamp LIST) but Explore shows all tracks with the same name (file's name=LIST name) ... Waypoints are ok.

Do I have to save  only one track per file ( and name the file the same as the track? Tha would mean creating one "Basecamp LIST"  per track? Come on Garmin!

Thank you,
