Repetier auto bed leveling wrong nozzle height

When I run G29 the probe runs the check at 3 different points and I think auto bed leveling is then set up correct. My issue is that the distance between the nozzle and the bed is always wrong.
It doesn't matter what value Z_PROBE_HEIGHT has, the distance is always ca. 8mm.

Here are my settings:
#define FEATURE_Z_PROBE 1
#define Z_PROBE_BED_DISTANCE 5
#define Z_PROBE_PIN Z_MIN_PIN
#define Z_PROBE_PULLUP 1
#define Z_PROBE_ON_HIGH 0
#define Z_PROBE_X_OFFSET -26
#define Z_PROBE_Y_OFFSET 7
#define Z_PROBE_WAIT_BEFORE_TEST 1
#define Z_PROBE_SPEED 2
#define Z_PROBE_XY_SPEED 30
#define Z_PROBE_SWITCHING_DISTANCE 1
#define Z_PROBE_REPETITIONS 1
#define Z_PROBE_HEIGHT 40 tried different settings but it doesn't change anything
#define Z_PROBE_START_SCRIPT ""
#define Z_PROBE_FINISHED_SCRIPT ""
#define FEATURE_AUTOLEVEL 1
#define Z_PROBE_X1 0
#define Z_PROBE_Y1 0
#define Z_PROBE_X2 100
#define Z_PROBE_Y2 0
#define Z_PROBE_X3 50
#define Z_PROBE_Y3 80

Same problem here.
Can't make Repetier Z Probe work.

And if you look for "Z_PROBE_HEIGHT" in the source code, it is used nowhere… It's not a bug it's a hidden feature!!!
:-(

I think I found out why it did not work on my printer: in the configuration my endstop z-min was the same as z-probe pin and I was doing a G28 X0 Y0 Z0 before probing.
I disabled z-min endstop (and so I updated to G28 X0 Y0 only). It seems to be working now.
