After you rename a listing in your PMS, the property page on your website shows the new name in its title, but the URL still uses the old name.
Why this happens. A property’s URL is set one time, when the listing first syncs onto your website, based on the listing name at that moment. By default, the URL does not change automatically when you later rename the listing in your PMS. The page title updates on the next sync, but the URL stays at whatever it was originally.
This is most common with older listings that were renamed after they were first added to your site.
