I made a tutorial on how to create a V4 Clone for Dawn, but some folks are having a problem on a certain step where they open the Properties Editor, and pick the Content Type.  On mine, it is as shown, and has a list of modifiers, so I can pick "clone".  On theirs, they just have "None"

Any thoughts on why one would just have None.  One person thought it was related to not having the CMS running.

Thanks for any tips!
