title: YDrive,XDrive,and ZDrive don't show a mode dropdown (Unity Editor)
body: <p>I am trying to learn to build a game with unity and the video tutorial I am following shows him changing the YDrive mode to position and as I went to do that I noticed that My YDrive along with all of the other drives did not have a mode that I could change.  I was wondering if anyone else had this problem and how you resolved it. Thank you very much for your help.</p>
