@Tess31 Your 3 listings are single rooms in a house however your description states that 3 ROOMS are available. I think you might intend for the whole house to be booked sometimes or individual rooms be booked. If so, add another listing that is specific for the entire house. Be sure to sync your calendars. Also, delete 3 ROOMS in your description of the individual rooms.
You have some terrific pictures of the external and the community but need a few more pictures with captions that describe what the guest has private access or shared access.
Let him cancel as soon as possible so you can correct the confusion and be more clear about what you offer. Do not cancel for him as you will be penalized for that cancellations. There is a tutorial about multiple listings on this site under Help. Look it up as I think you will find it helpful. GOOD LUCK!!
