I'm trying to simply move any vertex/edge/face up or down but visually it does not move. I see values changing when i'm moving them but ultimately nothing occurs visually. Additionally, if I try rotating a face so that one edge goes up and the other goes down they just pinch together instead (Imgur link shows what happens when the red rotate ring is moved). I can move the entire object normally up and down outside object mode. Using Blender with Maya config (I used Maya years ago for about 3 years.)

Any help appreciated, thanks.
