Your booking widget shows certain dates as available even though those dates are blocked in your PMS and the reservation is confirmed there.
Why this happens. HomeRunner stores its own copy of your property availability and syncs it from your PMS on a regular schedule. In most cases, a difference between your PMS and the website has one of two causes: a recent booking or calendar change has not yet been picked up by the sync, or the website is displaying a cached version of an older availability check.
What you can do. For most sites, this corrects itself within the next sync cycle. If you do a hard refresh of the property page and the blocked dates still show as available after several hours, contact support with the property name and the specific dates. Support can check the sync status for that unit and correct the availability if needed.
If the reservation is confirmed in your PMS and shows correctly on your PMS calendar, the issue is on the sync side between your PMS and HomeRunner. It is not caused by anything a guest has done.
