Dear Paul
The Airbnb website and Airbnb apps both are pulling the information from same web server. Some time the server takes time 24 hours to 72 hours for refresh the cache memory.
You may clear your device cache and try to view again and hope it will show the same in both place.
If you found not same after 72 hours of the published or listing update time you may contact with support@airbnb.com
Thank you
Regards
