Hi James,
You should head over to the forum on http://forum.makergear.com/, that's much more active than the Google group.
The Z axis moves up when you click minus, that's correct. You're changing the distance from the nozzle to the print bed, so adding 10mm should increase the distance, and that would cause the bed to move down.
