Encyclopedia bug

I don't think the Encyclopedia entries are showing up as intended. When I was double-checking my links for my webcomic site (almost ready for launch), I noticed that all of the pages display the entire A-Z list vertically, sometimes twice. Not only that, but it seems like at least one letter is always fully expanded regardless of the page. I can't find any real pattern to this bug. On the Abyss page, the T is expanded, while on the Sigil page, the E is expanded.

I'm using Firefox 3.0.11, if that makes a difference. I was going to look at it on IE but my IE is being veeeeeeeeeerrrrrrrry sloooooow since I upgraded to IE8.
