Model tree insert bar disabled (grey) Unknown root cause

[tbraxton]

Creo Parametric 7.07.0

The insert bar is disabled without known cause. This is one example where it is grey until I expand a group immediately preceding it and then it goes active. I have had different scenarios cause it to go grey that do not make sense. This is the first one I have captured and documented.

Has anyone else experienced this In Creo 7+? The only thing I found in the knowledge base was a reference to a corrupt creo_parametric_customization.ui file. 

This is in part mode. The models are proprietary so I can not post them. Example of what reactivates it in the tree.

I have run into this situation.  If the Group is expanded, dragging the insert bar up to below the last item in the group will place the insert bar in the group.  With the group collapsed, the active insert bar cannot be seen.

Dragging a feature also acts similarly with groups.

I suppose it may be working to spec but I find it frustrating. I will inquire with support if I am not able to find some documentation that brings me up to speed on the intent of the new UI in the tree.
