Litchi CSV export doesn't contain RTG altitudes but KML does

I have come back to Litchi after about a year and am getting peculiar results with the export option.

I use relative to ground (RTG) altitudes and in the Litchi app I see both the relative to start (RTS) and computed RTG altitude at each point on the map (see attached image). Also when I save the flight and load it in Missdion Hub, and click on a waypoint a message (eg. Ground Elevation 458.8m (57.1m below first waypoint) is displayed.

So the Litchi flight appears correct.

If I export to KML the altitudes appear to correctly follow the terrain.

If, on the other hand, I export to CSV all altitudes are output at the original altitude (101m) before I did a batch edit and converted frome Home to Ground.

I use these CSV files loaded into QGIS for display and I have checked files created a year ago in the same way and they have the correct RTG values in the altitude column.

I am at a loss to understand what I am doing wrong.

Any help appreciated.
