My guess is that your names are too long. Delete all the prefex crap that means nothing from each track. If you exceed name length with identical characters it will just replace the first one with the second one, etc. but you should get the last one. One has to go.
Be specific what you are doing,
Clear all saved tracks (20 now available)
get pop up
Get sucessful note
go to GPS look at track page and wee how many tracks are there
I have GPS class on my web site DualSportWest.com that may help you.
