Grass growing upside down on a plane

I have grass set up on a plane and it looks fine in the viewport render (when I hit command R) But when I go to render it to the picture viewer, it appears to be growing in the opposite direction. Doesn't make sense. I can't find anything that will solve this in Google.

Edit - Dynamics was checked on so it was causing the hair to bend downwards and grow on the opposite side of the plane. I unchecked it and it fixed the problem. Thanks Lazores!
