Even more info:
Here is the scenario:
1. I set up all the plan views & a few elevation & sections as the team leader w/ exclusive access.
2. Then, a team member started creating some additional details.
Since in the view set, the details are in a cloned folder, the views were getting added to the view set.
Those views could not be redefined (for scale, layers, etc) until the team leader did it.
3. The content of the details was pasted in from some of our old standards, with old layer names.
Once again, those layer couldn't be deleted until the team leader did it.
4. Then another team member signed in. All the plan views lost the layer combination toggling when changing the view.
Note: all the views created by the team member are visible to everyone else (unlike in V7 where they seemed to get lost).
We are linking to the PLA in the LBK. The views, when updated, do reflect the fact that the layer combination is now wrong / not toggled.
