Issue
When a library is selected in the DMS tree view, the sub folders shown in the list view are from different library.
Background
MacroView DMS use the title of the selected library in the tree view when determining the items to display in the list view.
Where two or more libraries under the same site have identical display names (title), even though the URL for each is different, DMS will display the sub folders for the first library it finds in site with the title matching the title of the selected library.
Workaround
Change the display name of the libraries to ensure that they are unique.
