Valo theme in Liferay 6.2 Portlet

I created two portlets side by side on liferay using vaadin and applied the valo theme to these portlets. I was expecting both portlets to be responsive. One of them tuned out to be responsive whereas the other did not.

Please see the screen shots. The vaadin portlet with the non responsive sceen (mobile2.png) cannot be moved or scrolled. What am I doing wrong?

BTW. Thanks for the great valo theme. It looks and funtions great out of the box other than the issue mentioned above.
