Takeoff height mismatch, copter

Hardware:

Cube Orange + Kore carrier board
Here4 GPS/Compass (DroneCAN)
Herelink telemetry
ArduCopter v4.5.7
Downwards facing lightware lidar lw20.
Frame: Quad X

I sent drone to takeoff from qgc (using herelink controller unit) to 2.5m using slider but it went off to about 10-11 meters. In the logs I can see that barometers data, CTUN.ALT, DALT, TALT, are almost same and also RFND.Dist also matches the graph. So I can say that drone was commanded to go to that height (appr. 10m). What could be the problem?

here is the logs file

changing this parameter solved the problem. PILOT_TKOFF_ALT = 1cm
