Why is the Delete option missing for old campaign drafts?

There is supposed to be a "Delete" item on the "..." menu (adjacent to "Copy" or "Edit"button) and also on the "Actions" menu -- see the screen shots in the knowledge base article 5680: https://knowledgebase.constantcontact.com/articles/KnowledgeBase/5680-delete-a-campaign 

Below are screenshots from my account. As you can see, there is no "delete" item in either menu. What the what?? Thanks in advance for help.
