Not moving below Z0 when Mesh Bed Leveling is used

I use the latest Marlin bugfix 2.0.x. With version 2.0.1 mesh bed leveling (MBL) worked without problems.

But now I have to disable the software end stops with M211 S0 and I did the MBL without problems. Then I sent M211 S1 to enable software endstops.

Have I to put M211 S0 in my START Gcode script in slicer in order MBL to work when printing and to be able the nozzle to go a negative Z in first layer ?

did you forge to set Z_MIN_POS?
The position of Z after homing (regardless if using a probe for homing or not)

#define Z_MIN_POS 0 - set to 0
//#define Z_AFTER_HOMING 10 - not activated
I am not using a probe. I use the classic piece of paper.
I attached my config files. My printer is JGAurora A5.
