I experience exactly the same problem. When I import the CSV file, say with the following basic data, it does not appear on the map:
Lat Long City
40.714623 -74.00660 new york
The software even recognizes Lat and Long and automatically suggests these columns to be classified as Location/Latitude and Location/Longitude. But when I finalize the import, the result does not show on the map (in this case nothing shows in New York area). Either I am missing something big time or there is a major issue with user unfriendliness?
When I classify New York as Location/City, it shows on the map...no clue why this works and lat/long doesn't...
Thanks for your help!!
