New Lists Changing Previously Created Lists: Potential Parent Hierarchy Issue
We are encountering issues where lists which were previously created have been changed when a new list is created.
The "New List" is has the "Previously created" lists as its parent hierarchy.
For example List Named "Department D2" is correct. A subsequent list called "Department D3" is created which has Department D2 as its parent hierarchy.
Once list Department D3 is created it changes the "Tree view" & "Grid view" of list "Department D2".
