Hi @Barry11,
If a person scrolls over that "Free Additional Guests" tab, there is an explanation that pops up. Although they explain clearly what that means, many guests will not scroll over it and/or read it. The only way of getting rid of this is to charge for the fifth guest. You could go in and charge the minimum amount but this may decrease bookings for you since you probably already priced your listing for 5 guests.
