that is because there are much more listings for smaller groups then for bigger groups. And if someone search for 2 people then smaller listings will be on the top of the search and larger, more expensive ones will be at the end.
I think Airbnb shows up to 300 listings per area so if there are a lot of units some of them will not be shown at all until you zoom in the map.
However your listing will be shown if your guests use filters , for example if 2 of them would like to book 2 bedroom home with parking and washing machine and you offer this amenities (just an example)
