Rooms

Hi,
why when I choose 2 adults and one night for example, the result show every room (double, triple, quadruple) and the tariffs that should be only for 2 nights?
I have set the rooms for minimum 3 adults and the complex tariffs setted 1 for one night and another one for 2 or more nights.
If you want to test it anticalocandadelborgo.com
Thanks

Partialy Solved! The error was in maximum and minimum night. I didn't think that it was necessary to set the minimum night for 1 day offer, or the maximum night for 2 or more night offer.
Now remains only the problem that regards person in room. If I search a room for 4 people for example it shows also the 2 and 3 people rooms, or instead if I search a room for 1 person it shows also the 3 or 4 people rooms.
