@Elizabeth1723 Did the 24 hour window for you to accept or decline pass while you were still "haggling" with this guest? If so, the dates would be blocked because that's what happens if you don't accept or decline within 24 hours. You can unblock them.
It's rather confusing as to what you are saying. Which request blocked your calendar? Were they both Requests or was one an Inquiry?
FYI you really shouldn't let a request from a guest who insists on haggling and asking a long list of questions, the answers to which can likely be found in your listing info, sit there preventing other bookings and wasting your time. Just decline them and move on.
