Sorry that you're having issues here. First, I guess I need to know what you mean by playing around here. Have you changed the listing template? If so, what did you change it to? Since the "standard" template (which I assume means the regular stock BD template) seems to work, I would suppose that something you changed may have affected the columnar display here. But not knowing what that is, I can't say off hand.
Have you seen this article here? http://businessdirectoryplugin.com/support-forum/faq/customizing-bd-to-fit-your-theme/
It may help provide some guidance as well.
