How can I remove drafts that cannot be resumed (page not found) and discard has no impact?

[Ruth Halbach]

In my drafts list, I have many listed as Untitled This draft has no content.  If I choose resume, I get a message that the page does not exist or I do not have access to the space (permission is not the issue).  If I choose discard, it seems to have no impact.  I would like to clean these up so that when I look at my draft list, I'm truly seeing items that need attention.  thanks in advance for your advice.
