[Therion] Trouble generating kml

Hi guys, This is the first time I encounter that issue. No warning whatsoever, the marker is at the right place with the name of the cave, but the legs of the survey are not in the kml file. This is a simple survey without th2 drawings, only legs and LRUD values. If I generate the map, profile or .lox of the cave it works fine. Has anyone came across that, any idea on what I’m doing wrong ? Thanks, Phil
