Odd inductive sensor triggering issue - z axis min

So, if I home through the smart controller display in the "prepare" menu, everything works normally and correctly. Everything homes then I can bed run the "bed leveling" and that works normally as well. The problem comes in when I try to print. X and Y home fine (they use optical end stops), then Z does it's first bump, the sensor triggers then the plate moves downwards. The LED on the probe stays turned on and plate doesn't return for the second homing bump. Then the printer just continues on with the printing. The probe LED indicates triggered even though it's 10 mm from the bed though the z-axis says it's 0 on the display. This happens when I try to print by SD or USB. Once the probe gets locked up like that, it won't even home through the prepare menu anymore. I have to reset the printer or power cycle to get it to home correctly again through the menu. Has anyone else had this issue?

#define Z_PROBE_OFFSET_FROM_EXTRUDER 0 // Z offset: -below +above [the nozzle]

you need to set this to 10

The offset is set to 4 since that's the offset between the nozzle and the probe but it had no effect either way.

Any other suggestions?
