I get the "currently configured first field will not be shown" message even though first field is DraggableView:Order

I've used draggable views before and never had an issue, but I can't figure out why I'm getting this message.

I have it set up as follows:
sort:
- DraggableViews:Order

fields:
- DraggableViews: Order
- Node: Title

Style:
-Draggable Table

Style: Override normal sorting
- tried checked and unchecked

Style: Order Field / Handler
- DraggableViews: Order / Native (also tried CCK)

What could I be missing? I know this has to be something obvious... but I've compared it with my other draggable views and I'm just not seeing it.
