They both look the same to me. Did you uninstall the hack? If you installed it then you should not see the "collapse" while expand is active.
It also looks like you have JC's templates, and I didn't write the instructions for those templates so you'll have to take the php script that I added to the default templates and copy it to the appropriate places in your template. Also keep in mind that since I used the default templates as the base for this mod any changes that JC has made to the CSS classes (and the places where those classes are used in the html) will cause conflicts with this mod (so it would be easier for you if you just used the php script additions in my instructions).
After looking at your site it seems that you haven't installed this mod...
