Try the same in Nevada.
You will be surprised, I promise.
In Nevada my Mark Points are allways on target. In the old DCS-Terrain my Mark Points are ALLWAYS off the target.
Independent on laser using and range to target.
Btw, if your laser dont get a range, your mark point is set to your actual position. Because the "measured" range is zero.
As soon as you get a laser range, the mark points are all in the way they should, on the ground not in the air.
