The Map Console only displays the members of a group when that group does not contain any child groups. If a group contains one or more child groups as well as members, only the child groups are displayed.
When you create groups to display them in the console maps, create a catch-all group within a parent group. The catch-all group should contain all the members that do not belong to any of the other subgroups. This technique prevents a parent group from containing both members and child groups.
