@Lindsay61 unfortunatelly, that is the penalty for cancelling a reservation. For the future you should either have the guest to cancel the reservation or call airbnb and ask for their assistance to cancel the reservation from their end because the guest wants to bring extra people more than what is allowed on the listing. For now, I suggest for you to contact airbnb and see if they can help you open the dates again as you were not aware about this. Good luck!
