Hi @Julie4741
This has been a "hot topic" in the Community as @Paula mentions, since the Summer 2023 Release. Did you by chance opt-in early to the new release? Many hosts have had issues with the calendar settings being "stuck" on their previous custom settings for min stays and check-in/check-out restrictions. Some have mentioned "ghost" blocking/unblocking as well. Some hosts have only been able to resolve the blocking/unblocking issue by setting their availablilty to "Unavailable by Default" (this will not effect your current bookings), then manually unblocking dates as desired.
Looks like right now you have the 12-month Calendar set. If you have concerns about the unblocking issue, you might try setting your Availability to "Unavailable by Default" and then manually unblock the dates yourself. Many hosts do this anyway to ensure they have their pricing correct before dates are opened for booking. With the standard 12-month, or all available dates rolling calendar, it's possible you would forget to update your prices as dates open up one by one automatically as the calendar moves forward. Choosing Unavailable by Default prevents a Host from inadvertently forgetting to revise prices and subsequently getting a booking at a price that is less than desirable.
Not sure if you are using Pro Tools and Rule Sets? If you are, be sure you have not applied a Rule set that would override your blocking/unblocking attempts. You should be able to see if there are any notes about that if you click a date and look to the right panel. It would show if there were any special restrictions on that date in the right panel.
Hope this helps 😊
