Block when adding Superfish

When I add Superfish to the Menu Bar block, I get a color block in the top of the site.

When I inspected the page in Chrome I get
#menu-bar-wrapper in colors.css
background: #0a465;

But in the colors.css file the settings are:

#menu-bar-wrapper {
background: #2e2e2d;

I wish to set the block color to the same as the backgroundcolor for the page.

My site are: lysetskanal.dk
I use this versions:
Theme: Corolla 7.x-3.0-rc1
Superfish 7.x-1.9-beta5

Picture "Without superfish" are the site without Superfishmenu
Picture "superfish" are with the Superfish menu enabled.
Picture "colorcss" are the elemet inspected on the site

Thansk for your advance
