More weirdness with tab widget

I've inserted a tab widget into a new page on a blank project (no assets used) and it gets funny in the preview, will it come back to normak once uploaded? Why is the preview so stretched out and wierd? 

The first screenshot with the scarecro is how it looks in the authoring window, and the second with the potatoes is how it previews, none of the other widgets are doing this. 

* I had disabled the heading on the widget and it still appears in the preview as well.
