With regards to page URL tied to a page name value, it takes the associated URL of that first page name value seen in the given month. This means if multiple page URL's are tied to a given page name, only the first URL will open in the interface.
If you find that you commonly face this issue, I'd recommend setting a prop to something like s.propXX=window.location.hostname+window.location.pathname, then breaking down page name by this URL prop. You can then highlight the URL and open it in a new tab - this method also shows you all URLs where that page name is populating, which may be helpful in debugging.
