If you want to offer rooms, you need to create a listing for each room.
Each room will have it's own pricing and booking calender.
Your current listing is not correct:
1 guest can book all 3 rooms for the price of 1 guest
Or
A group of upto 8 guests can book all 3 rooms for the price of 1 guest
At least you need to set the extra guest fee for the additional guests:

I suggest to make proper changes to the listing before publishing it.
