Your booking site shows stale availability, and it only corrects itself after someone runs a manual sync.
Why this happens. Your site stays in sync through automated updates pushed from the HomeRunner backend. If those updates fail, for example because of a configuration issue such as an outdated webhook endpoint, your site does not receive the refresh signals it needs. It then shows stale availability until someone manually forces a re-sync.
What you can do. HomeRunner monitors for this, and support can identify and resolve the underlying delivery issue. If you notice that repeated manual syncs are needed, let support know so they can look into the root cause.
