Menu gapping on 2nd level for Studio theme

I activated my site menu using this theme, but when attempting to use it on the live site a problem occurs:

You can select the primary menu option, dropping down a menu. However, I have a second level of menu that flies out from that menu selection. When this occurs on the Studio theme, there is an approximately 30px gap between the 1st and 2nd level menus. When you mouse to the right to select one of those options, the menus disappear when crossing that gap and there doesn’t seem to be a way to successfully cross that gap. The menu was working under the default 2011 theme. The problem is visible on Chrome and IE.
