"Choose your page navigation background colour" menu NOT Working

Hi,

I'm running a Wordpress Version 3.0.4 install with Product 2.2.2. I enabled the default.css to be able to customize the theme in the "Custom styling" menu.

I've been able to change all the elements on that menu but it looks like the

"Choose your page navigation background colour" tab doesn't work.

When i pick my color code and save the options , i update my page but it makes no changes on the theme.
