I have a Garmin Montana 650t and none of the 44 tracks are appearing in The Track Manager. My screen has Current Track then Archived Track then my 44 different tracks should show up.  It's just blank. I have a few in the Archived bucket so the screen is working but I don't know how to get the other 44 tracks to show up. If  I hook the Montana to my computer using base camp they will show in my computer so they are still in a the Montana Garmin.gpx file.  Has anyone had a similar problem. Is there an option that I turned off that is keeping the tracks from showing?
Thanks for any help
