Please try the following ...:
*Mark 1 single waypoint on the Humviewer playback ...
*Select "Tools" in the upper left ...
*Select "Show in Google Earth" ...
*Select "OK" in the "What to include export" window ...
*Post a screenshot of what Google Earth displays ...
(My Google Earth is only displaying the single label I entered when creating the waypoint in Humviewer) ...
