Active State for Top-Level of Sliced Menu

I have installed the sliced menu module so that I can have a top nav and a left nav for my site. I previously had to create individual menus for the left-navs and a separate menu for the top nav. With this module it appears that I can contain everything in one menu. However, I noticed that even if I click on a second level nav item, the active state is lost for the top-level nav. When I view the source it states in the li class that the top level is "inactive". Any chance this can be fixed quickly? Or is it already working and I just might be configuring something wrong?
