Duplicate Pages

After being away from editing our site for awhile, I recently noticed that something was creating duplicates of the Directorist pages. As some examples, we have three “All Categories” pages, three “All listings” pages, and three “All Locations” pages. i assume they may have been recreated when the plug-in was updated, but I don’t know what to do with them.

They all have different url’s. The original ones list “Administration” as the author and the other ones are blank in the author column. My question is this: Can I delete the extra ones? We have a lot of extra pages now.

Thanks for your help,
Jane
