I made some changes to printGroups to use same "seen trick". Won't print the same $groupData{$group}{line} twice. Could be some flaw here, but this is a quick way that looks like it produces the desired output. 
my %seen; ###

sub printGroups {
    my ($groups, %groupData) = @_;

    for my $group (sort @$groups) {
        next if !exists $groupData{$group};

        if (!$seen{$groupData{$group}{line}}++) ###
        {                                       ###
           print $groupData{$group}{line};
           print @{$groupData{$group}{data}} if $groupData{$group}{dat
+a};
           printGroups($groupData{$group}{groups}, %groupData)
               if exists $groupData{$group}{groups};
        }                                       ###
    }
}
