Why only show the parent node does not reveal the child node

Who can tell me:
I was so used:

The problem:
1.Show only the parent node, child node does not show ???
2.If I use the Professional Edition will not avoid this problem???

I hope to have all proposals

Show only the parent node, child node does not show ???

You’ve already asked this question. And the answer is “3-state checkboxes and Smart Rendering are NOT compatiple”.

If I use the Professional Edition will not avoid this problem???

Smart Rendering is avalable only in PRO edition. You are not allowed to use this extension without the license.
