Strange behavior when building a table heightmap

So, my setup
VCore 3.1 500

Manta M8P v1.0,
TMC 5160 on each motor
Toolboard EBB36 v1.2
Rapido UHF
TriangleLabs Bltouch
8mm builplate

And ive strange behaviour when i'm trying to make a Height Map

He does not seem to take into account the bltouch offset, i.e. conditionally the nozzle is in the right place, but BLTouch in the standard configuration tried to make changes outside the field.
