Categories not showing on home page

I have installed the directory plugin and am using the default directory theme that comes by default with the plugin. With the older version of the plugin the categories were showing up without any issues. But with the update version 2.1 by "By Alexandros Itsios" i am not able to get the categories to show up on the home page. Need help with this.

Thanks and Regards,
Alagiri Rajesh
