Hi @Doreen16 , it looks like a great listing!
Firstly, are you aware that Airbnb hide some of your info?
"about (Phone number hidden by Airbnb) I was I...dabble in art (landscape painting) as a hobby but i don't claim to be good at it. I am on (Hidden by Airbnb) and my website is (Website hidden by Airbnb) "
I would address these issues immediately. It looks suspicious to renters.
And; regarding the booking window - it may be as simple as the venue being blocked for 1 night before a reservation. As this is an automated system, I suggest that no amount of overriding would work.
Good luck with your investigations.
Cheers, Charles
