It looks like the distribute options are being merged. I suppose that they could be incorrectly setup, so you should double check that.

I did some more digging. What I'm getting is a bit strange. So it seems the reason things look broken is the function gpii.uiOptions.enactors.cursorSize.set can't find the cursorDiv. What's really strange, is that the container for this specific preview appears to be on the Magnification preview instead of the Cursor Size preview. You should double check that when you save that something strange isn't happening with the containers for the components and subcomponents.
