Perhaps potential guests are confused by your listing. It appears your listing is not set up correctly for this platform. You need a separate listing for each separate bedroom with the appropriate pictures and room description. Then you might want to have a whole house listing in case a larger group wishes to book. Then you will need to sync the calendars of all listings.
There are many discussion threads about multiple listings for the same address. It might be useful for you to search this forum for these discussions for ideas. Good luck!!
