Classifieds plugin not displaying properly and creating too many pages

For some reason I'm having extreme problems getting the Classifieds plugin to word properly. Apart from some terrible styling issues, it has created 9 'add classified' pages, all of which just show the 'this is a virtual page' text and nothing else.

When I try to add a classified ad via BuddyPress, it seems to be okay until you reach the bottom of the page, then this text shows;

[custom_fields_input" style="editfield"]

Also, a create ad button doesn't show on the classified ads page.
