How do I turn off the snapping with the new alignment guides? FV-36

I see you just added alignment guides. But it's causing me to not be able to move my image on the App Store screenshot to the position I want it to be in. It keeps snapping to the middle of the screen. No matter what I set the Alignment option to. In my attached image, I want the Mac to move down a few pixels. But I can't do it. It goes too far and when I try to bring it back up, it snaps to the position in the screenshot. There's no "None" option for Alignment to turn off the snapping guides.
