Bltouch probe doesn't deploy/zero on G28/G29

I've wired my bltouch probe into the Z_MAX port on my SKR 1.3, left the Z axis stop switch in Z_MIN, and changed the settings to match. The probe lights up, deploys, retracts, selftests, reacts to input, and I can get TRIGGERED outputs from all three axis stop switches and the bltouch probe on an M119 command when depressed. The Z axis stop switch will still work for a G28, but I can't get the probe to deploy when it is homing or when it is doing bed leveling. Removing the Z axis stop switch, putting the probe in Z_Min, and changing the settings back doesn't work either, still won't deploy on homing or leveling, though it reads as Z_MIN instead of Z_PROBE during an M119 command

I remember having a similar problem like this on marlin 1.1.9. Not sure why but changing from AUTO_BED_LEVELING_BILINEAR to AUTO_BED_LEVELING_LINEAR and enabling Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN got me going. not shure about 2.0.x
