You can clear the list so Real User Monitoring Insights will try to scan these pages on the next scan.
Real User Monitoring Insights only looks at pages that have been scanned by Real User Monitoring and your results will be more accurate and easier to follow if you have wildcarding set up. The main issues are duplicate pages being created by default for the same view (due to the REST routes and other schemes) and multiple domains.
Documentation on setting up the wildcarding for grouping URLs and for subdomains can be found in the Real User Monitoring documentation.
