Ok that looks correct. So these rogue contacts are just on the Mac and not the phone?
You could try logging out of icloud on the Mac and then do a restart of the Mac and then re-sign into icloud to see if everything resyncs including contacts.
Or try some of the suggestions here if that doesn't work

Hi again,
None of the above worked. I have even tried signing in with someone else's iMessage account (iCloud!) and the old contacts appear so I'm guessing they must be held somewhere in my MacBook? I'm still confused as I don't know where - they aren't in my address book or anywhere obvious to me...!
