Dual Axis Z1 moves in same direction for all moves

I have a configuration for a dual Z axis using a SKR 3 EZ. When i try the STEPPER_BUZZ STEPPER=stepper_z1 command, or try homing, the motor moves upwards even when it should be moving downwards. It also moves upwards when it should be moving upwards.

At first I thought it was wiring, but since i confirmed proper movement on the other Z motor, I swapped the cable completely, and it still does it on Z1 motor. I also plugged Z1 motor cable into Z motor, and when I do it only moves in one direction.
