Sovol S07+ doesn't save negative z_offset correctly - firmware bug

Addition: I bet this guy has the same problem

Can't get the probe z offset to work on sv06

Did anyone find a solution for this? My sv06 out of the box does absolutely nothing when i cluck on the z offset. The numbers on the screen change. However the head does not move up and down. I have to fake the numbers in configurations to get it even close. Yes i scratched the bed. Made me super happy on brand new machine
