Hi Dawson,
Just to clarify, would you like to see a site map tab similar to the one under Target > Site map in Pro? If so, can you share a little more detail on your use case?
Have you checked out the 'Scanned URLs' tab in Enterprise when you select a successfully completed scan? This gives you the option to display the scanned audit items in a Tree or List view - I think the Tree view may be the one you are after.
The troubleshooting documentation can be found here:

However, I would recommend emailing us at support@portswigger.net if you face any issues so that we can assist you as quickly as possible.
