I can't access the Theme Options in Buddypress Fun Theme after update to Wordpess 3.6

When I try to access any of the theme option settings in the Buddypress Fun theme, it just stays on the first tab regardless of which tab I click on. It tells me that I must have the default.css selected in the BuddyPress Fun Preset Styles section, but there is no way for me to access that.

I just upgraded to WordPress 3.6. I don’t believe this was a problem before the update.

See the link below for a screenshot of what I am experiencing.
