Latest WP, fresh install, wp-survey and quiz too being the only active plugin.
I create a survey with one section, one question. I put the shortcode on a new page, then I load the page.
The content is there, but scattered with tabulations everywhere. As I look at the html code behind the page, I can see a lot of TABs, and the browser display them all on the page.
Tested with firefox, IE and Chrome.
