Thanks.  Yes, I did.  The 'Extended view' checkbox is checked.  I also
checked other pages, some do have '[Ref]' column in the list view, but it
only shows the number of reference rather than reference names.  The list
view doesn't show this to-be-deleted page has any contents.  That made me
wonder where the reference came from?
