Unable to delete added menus from admin bar

For some reason, Ulimate Branding has duplicated a menu item I added to my admin bar.

See here: http://teatra.de

It gets worse though, I can't delete it, which is the bigger issue. In the settings area, when I click the delete button, all it does is expand the options metabox for that menu (as if I was clicking the open/close arrow, just next to it). Is this a bug in Ultimate Branding?

I can provide some login credentials if needed so you can see the behavior in action. Are you able to recreate this in your test sites? I have it setup on a multisite install.
