Height being rendered wrong?

Hey guys

I am approximately 1000 meters from sea level. Flights with flight height changes are rendered correctly (example: attached mission-2). However, with flights that do not change altitudes during the path, they are rendered 1000 meters above (example: attached mission-1).

I think it is something related to relative and absolute height.

When selecting the altitude using the GPS, the trajectory is ok. Still, the white dashed lines continue pointing to 1000 meters above.

Start by reproducing the discrepancy with the linked sample missions and logs, then trace how constant-altitude flights and the white dashed lines derive their heights. Done means the rendered path and dashed lines align with the GPS-selected altitude as well as with flights whose altitude changes.
