My macro, in the revised document, shows 1 list and 22 list templates.
Code:
Sub NumberOfLists()
' Charles Kenyon 16 April 2022
MsgBox ActiveDocument.Lists.Count, title:="List Count"
MsgBox ActiveDocument.ListTemplates.Count, title:="List Template Count"
End Sub
In a new blank document, the same macro shows 0 lists and 0 list templates.
In your originally posted document it showed 2 lists and 22 list templates.
