Page layout totally messed up

Hello,

Just installed this great plugin and have start the work on creating a books directory.
As you can see on our listings page http://blog.queermagazineonline.com/listings/ the layout is totally messed up.

I'm guessing this is caused by the template we are using.

Do we have to change template to get the directory plugin working or is there any other solutions?

Thanks!

Anders
