Try creating a new group but this time with a number at the beginning with an underscore between it and the group name based on the order you want them from top to bottom....a "1" will be sorted by BI to be at the top, with "2", "3" and so on after it.
IOW, if you want "Backyard" to show first, name the group "1_Backyard", if you want "Apartment" to show up second, name the group "2_Apartment".
Add the desired cam to the new group.
