Facility type

I just joined Booking.com

My Hostel is renting bunk bed per night. A1 LA City Hostel in Los Angeles. After I set up I went online to see the reservation page. It shows my accomodation type is 8 beds mixed dormitory room. Sleep 8 but the column for the selection says select room instead of select bed. How do I modify this? Did I set up wrong accomodation type? Please help

Thank you,
