Having very strange issue with categories and page layout

[strangeclosets]

Hey everybody, I appreciate all your help so far. I've been able to accomplish more than I would have thought because of your help. I'm rolling out the site soon and I have one final question.

For certain catagories (but only a few) the sidebar (email subscription box, adsense, blogroll, etc.) gets pushed down to the very bottom of the page. For example, go to http://www.tategunnerson.com, to the Strange Musings tab and then click on Decoratus Absurdum. It also happens on a few other categories (Shopping Guide then pick Lakeview, Lincoln Square and West Side subcategories for example).

Shouldn't the page template carry through to every page or category no matter what?

Also, for a couple of the pages the sidebar header bars are in italics (tategunnerson.com, then go to interviews and click all interviews).

I'm very confused, but I appreciate any help. Is this a code issue?
