Superfish menu hover background color when using multi-column

I'm using AT w/ superfish and using multi-column submenus. When I am hovering over one of the submenu options, I am getting weird "bleeding" background color effect on the other submenu options. In the screenshot attached, the mouse is hovering over Test3-1. The other background colors should all be dark gray #333333, however the bottom right shows up in red, and the other menu options look like #333333 but seems slightly tinted red. I'm really trying my best to describe this. Does not appear any css is causing these effects, as there is no "#333333 tinted red" color in any of my css.

Thanks!
