Interior elevation creation, saving adjustment to associated clip volume

I use interior elevation creation tool in an enlarged plan drawing file.

The interior elevation saved views are created and stored in the composite master model (cmm).  I adjust the extents of the clip volume and properties geometries extent.

When I reopen the enlarged plan drawing file I immediately notice the cmm is locked and being written to.

When I go back into the cmm, I see that all of the clip volume changes that I have made have been undone, and the views are reset to their extents at the time of creation in the drawing file.

I would appreciate ideas on what is causing this and how it can be prevented.

[25-January-2017 Update] Clip volume associated with interior elevation saved view created in the cmm return to default extents (extents at the time of creation) when adjusted with the plungers or modified within the Saved View properties.

Thanks!
