I am trying the new predefined css classes and page breaks with my form at http://www.decoridesigns.info/gravity. When I preview the form after saving, everything shows up how I defined it. (3 column lists on the first page, email and phone number next to each other in a 2 column layout on the second page, and a progress bar on the top for step 1 and step 2) When I go to the page with the form, none of the custom classes are working. My lists are in 1 column, my email/phone are in 1 column, and the progress bar doesn't show at the top of my form pages (just text saying which step it is and progress percentage).
Since these features are new, I'm assuming there's some sort of bug that needs to be fixed.
