Error in displaying multiple children on same line

RobinsonGaryCraig1

On my tree, I added my children and then their children (my grandchildren). When I look at my children, each of them has a carrot underneath. When I click on the carrot for one child and the grandchildren are expanded, it looks fine. If I click on the carrot for another child, the grandchildren are displayed but they appear to be added to the previous list of grandchildren. One solution would be to eliminate the expanded view for the previous child when I select a new child to show the expanded view of their children. Otherwise, more space would be needed to separate the families when multiple children are expanded to show their children.
