What can I do here?
Use this window to manage the list of URLs for which you have overridden their initial categorization.
Getting Here - Object Explorer > New > Custom Application/Site > Override Categorization
When the category data in the Application and URL Filtering Database for a URL is not applicable for your organization, use the override categorization option to update the category and risk definitions of a URL.
