Blogs Directory generating wrong HTML

I installed the plugin Blogs Directory, but it generates the HTML on my site with error. Look at the pictures attached.
Arrow 1: when you click on the menu to list the Blogs Directory, it seems that duplicates the menu.
Seta2: On the title page appear this quotation marks.
Arrow 3: Using Firebug, look at the code of the title above.

Here are some information about the environment where I am testing:

Wordpress version 3.0.1, using multisite. The BuddyPress is installed, but it is disabled. The version of Blogs Directory is 1.0.7. I'm using BuddyPress Social Child Theme 1.1.8
