How to fix notification bug in MPMUDev BuddyPress Themes

I am using the BuddyPress Social Theme and have a bug in the rendering of the notifications tab.

To reproduce: Clean install of WordPress, BuddyPress and BuddyPress Social Theme. No other plug-ins active. Click the "Notifications" link at the top of the web page.

I expect to go to a page that shows my notifications.

Actually I go to a page that shows the notifications toolbar twice and no notifications.

A similar issue has been reported in the BuddyPress forum. The advice was that the theme was buggy.

* Please tell me how to fix this bug so I can see my notifications

Kind regards,
