Treeview sync ignored for mapped drives

Despite Treeview option enabled to auto sync with main pane (listview), this left pane only updates when I am on the C: drive, and completely left alone when using eg. non-local Q: drive either in same tab, or other folder tabs.

Treeview does not update folders (and remains showing C: drive) while I am operating on Q: drive on right side, changing folders within Q: drive.
