inquiry still block my calendar

[Emmy--N-Sis0]

I got one inquiry from guests and I sent them pre-approve. I asked them to accept but they said they cannot accept pre-approve to confirm reservation. They ask me to decline them first then they will startover again. 

After I decline the calendar still block on that period in their name. They cannot rebook again.. They waited me for a while and booked at another place already. 

I want to delete this booking and make my calendar available for that period again. 

Anyone knows how to do, please advice.

Many Thanks

Hi Emmy, Did you figure out how to do this? I have the same situation. My calendar is blocked from an inquiry. -Cindy
