Number of guests

I'm confused when I break down the details of reservation and it says "Max occupancy

10 adults, 9 children (max 10 guests)". Are they coming 19 people?! We can host 10 people and we have set our limit to 10 guests. Are children not guests?!  In basic information of the reservation is "Length of stay: 3 nights Total guests: 10 adults". It's our top-of-the-year time to host and I would like to make it clear as soon as possible. I have never had this kind of problem before.


Looking forward to your answer,
