Z Motors turning on retract/unretract

I'm not trying to cross post, but I'm really being stymied by a problem and I didn't see this particular section before posting to the printing section.

On retract/unretract my z motors are turning which after some time causes my print to fail miserably. This started happening very suddenly a few days ago. Normal extrusion doesn't cause any issues.
