Hi Sebastian! This is usually just a setting issue in your dashboard. Go to your Listing, open your Calendar, click on Availability, and check the Trip Length section to make sure your minimum stay isn't accidentally set to 10 nights. If your settings look correct, double-check that your tourist license details are fully verified under the "Regulations" tab, as Airbnb sometimes restricts calendars if paperwork is pending. If both settings look good and it's still locked, reach out to Airbnb Support directly to clear the glitch.
