[BUG] (Bedleveling fails with Z_AFTER_PROBING < 100)

[Vasco-Da-Gama-png]

Bug Description

I use the settings for my Creality CR-10 V3 provided by marlin: https://github.com/MarlinFirmware/Configurations/blob/release-2.1.2.1/config/examples/Creality/CR-10%20V3/Configuration.h

After probing, the print head always raises 100mm what is unnecessary and for a different feature I'm using unpractical as well. Thats why I'd like to reduce that value. But reducing the value Z_AFTER_PROBING from 100 to 50 the probing suddenly fails. And I have no idea why and it makes no sense at all for me. The value seems also quiet high for me as well, as in other configurations its just around 10.
