Should be fixed now. 2.190.1
Fixed a KML track whose altitudes are heights above the ground being read as heights above sea level. A track made 5 ft above a road was drawn far under the ground. Such a track is now read as height above the terrain, and a track that the file puts on the ground is put on the terrain. A track with no altitude mode, or with parts in different modes, is read as before. A sitch saved by version 2.190.0 or earlier keeps its tracks where they were. The Select Tracks list and the Altitude Range (ft) filter now put such a track on the loaded terrain to get its altitude, and the Track Browser shows its height above the ground (#15182 "KML doesn't work as a track").
