Directory - List categories not displaying when using shortcode

Using Directory (with Custom Press) Ver., Membership Premium Ver. 3.4.2

Q#1: The shortcode [dr_list_categories style="grid"] does not work. Before we made any changes to Custom Press (that came with the Directory plugin) we could see a list of catergories on a page. After we made some changes like adding more categories and listing catergories the page no longer loaded the list. Does creating listing categories change the way the shortcode works?

Q#2: Also can you force the shortcode to display a certain categorie with its sub-catergories?

Please help! Thanks!
