[Plugin: Image Archives] Design #3 's div problem

I used the last version with WP 3.2.1 and I found a problem with the design #3, the div was nesting in another div, the page I used is here:

I’m really like this plugin and wanna use it with desgin #3, if it’s a bug please fix it, or tell me if I used it wrong way.

Thanks a lot!
