Not sure if this is expected behaviour.

To test sending routes via email,
I first exported a route as a gpx and a csv.
I then went to import then from the Marks Tab -->Import
When I import the gpx I get a success message and when I goto "Edit Marks" I see the route on left and a "gpx" folder on right with all of the marks in it.  All looks good.

When I import the csv,  I get no message indicating it was completed.  In "Edit Marks" I do not see a route on left.  On right side I see a new separate folder is created for each individual mark.
