Child items not deselecting in outline view

I have an outline with the new collection view list configuration set to sidebar. If I select an item at the root level and then disclose a node with children, I can select a child and the highlight of the outline switches to it. If I then tap the parent to hide the child and select a root item again, the highlight moves HOWEVER if I then disclose to display the child again it maintains its selected state and now it looks like my sidebar has two active values. How do I prevent this from happening?
