I created a route in MapMyWalk, saved it with distance markers turned off. When I export the file to .kml and open in Google Earth, a placemark and label for every one of the 220 miles appears. I can individually unclick each or these so they don't show. How can I do this globally? Or better yet how can I have the KML file without these placemarks in the first place.
A couple of years ago I did this without this problem.
