Your property page lists a twin bed as a single bed. Single is the website’s label for a twin bed. The bed count is correct and only the word differs, so nothing needs to change in your PMS.
If a bed is missing. If a bed does not appear at all, rather than appearing under a different label, reactivate or re-save the unit in your PMS so the next hourly sync picks up the room configuration. Then check the property page again.
