Q&A not showing on page correctly

I'm not sure what is happening, but for some reason, the Q&A isn't showing correctly on my site.

I've filled in all the sections in the settings, but it is pushing itself across the page on the left.

As well as the Q&A section being to far on the left, it also stretches the sidebar too far to the right, as you can see on any of the other pages.

I've attached a screenshot of my settings. The theme is Canvas, from Woothemes.

Thank you.
