No option other than Reset?

Hi --

I've been using Atahualpa happily for a few years and am migrating another site to WP and the theme; it was essentially ready to go, but when I went to make a couple more small changes on the Theme Options, the only option clickable is 'Reset' - the reset button has taken over the middle of the page, and obviously I don't actually want to click it - but nothing else is active.

I didn't see this issue anywhere obvious in the forums already, but is there a fix for this? I'm using 3.4.5, and I haven't tried any of the new options like the thumbnails - and the site looks totally fine at the moment, I just don't want to launch and have to rebuild immediately when I need to add a minor change.

Thanks!
