Duplicate contacts, cannot delete them, only on Mac, not iPhone, iCloud or iPad

[MacInWin]

I have four duplicates of MY contacts on my Mac. One of the duplicates has only my name and my Facebook login (which I never use), and nothing else. The other three have my emails, telephone numbers, etc. Unfortunately, the one with NO information is the one I cannot erase and which, if I select it, I cannot merge with the others. I don't have dupes on iCloud or my iPhone or iPad, just the MBP.

Running Sierra, 10.12 on a rMBP, mid-2015, all updated. iOS is at 10.0.2 on iPad, 10.0.3 on iPhone.

How can I delete the dupe that won't delete? Is there some way to make one of the contacts cards be ME for the system? It appears that the mostly empty one is currently ME.

I did search first, found a suggestion from Apple that said to merge, which I cannot. And the problem is ONLY on the Mac, not anywhere else.

Puzzling.

Just done what Apple suggests on my MBP (same specs as you) and it identified 18 duplicates for 13 contacts and asked if I wanted to merge. Did so no problem.

Could it be something to do with Groups?


Delete contacts or groups

You can delete contacts and groups at any time.

Open Contacts for me

Delete a contact: Select a contact, then press the Delete key.

If you select a contact who belongs to a group, click Delete in the message that appears.

Delete a group: Select a group in the sidebar, then press the Delete key.

If a group is used in a Smart Group (by including a condition that uses “Card is member of” or “Card is not member of”), you can’t delete the group until you change the condition or delete the Smart Group.

You can’t delete contacts in read-only accounts such as Facebook and LinkedIn; you must delete the contacts directly in Facebook or LinkedIn, for example. If you don’t want to see contacts from a specific account, stop using the account in Contacts. To do so, choose Contacts > Accounts, select the account, then deselect its Contacts checkbox.

If you stop using or remove an account, any edited contacts remain in your default contact account.

It was a Facebook account that put the bogus card there. I don't remember turning on Facebook, I wonder if it was "automatic" somewhere...in any case, deactivating it as you pointed out eliminated the dupes. Thanks!
