Forum title widths?

[shot2bits]

Evening All,
I'm not sure how my forum titles have become wide. I think they're called category strips.

If you look at the following pic, you'll see the title borders are double width? e.g. Where it says Welcome, The Bar and General?

Any ideas how to fix this?

Thanks, Rob.

You can make the CSS field image bigger ...
