non-refundable rate

Good morning everybody,

for my house I have set 2 different types of rates: a standard rate and a non-refundable rate with a 10% discount.

Yesterday I have had a reservation with a non-refundable rate but the reservation description says that the guest have the possibility to cancel the reservation.

Why this happens? What I have missed in my settings? What can I do to avoid this?

Thank you very much for your suggestions.

Marco
