When homing, z bed moves down before going up, crashing into brackets

Hey guys,

Just got my SmartrapCore printer up and running with the latest version of Marlin.

However, when I home the axes, my bed lowers 10-15mm before the x and y axes home. Although occasionally the x and y axes will home before the z axis moves at all, yet regardless the bed moves down a small amount before going up.

This is an issue because my bed is always at the lowest position possible when I start, so this causes it to crash into the brackets holding the z-rods in place. So then the motor is skipping and that belt is freaking out, etc.

So I am required to raise my bed by hand and hold it in place before homing so that it starts mid-axis.

Is there a setting I can change to fix this? I've also noticed that when I turn the printer on it shows the Z axis at -14.99 by default? So it thinks it's above it's zero position? So perhaps it tries to lower it 15mm before homing x and y?? I don't even know.

FYI, I have auto leveling enabled using an inductive sensor.

Thanks for the help in advance.
