Send a copy of the serach and results page, and i can tell you how to remove the validation.
the Create pages wizard cannot be used to edit pages, it can only be used to create pages.
To add the Unique Column validation to pages that are already created, you will need to edit the Server Validation server behavior, from the validation type, select Unique column value.
Thanks Jason. So there is no way to apply updates to existing pages, even though there appears to be a place to target them? The greyed out option is confusing.
