Suffusion theme, 2 right sidebars widget problem

Hi.

I have a website which uses one right sidebar as default. The front page of the website is the blog. Now, I want the blog to show 2 right sidebars instead of one, so I choose the option “2 right sidebars” sunder “Select the sidebar layout to apply to this post” at the bottom of the post.

Then I added some text and stuff, but nothing shows up. Anyone have an idea why this happens?

I also tried to choose the “2 right sidebars” in the template- option to the right of the post, but still my website only shows the 1 right sidebar

Anyone? Thanks
