I can't delete contacts from my contact list!

[Tricon7]

I noticed recently that I have all sorts of contacts in my Contacts list that I never put in there. Were they somehow automatically migrated from my Facebook page, I wonder? So I went to delete the contacts I would never email or phone, and though I selected Edit > Delete, their name is still present in the list! :>(( How do I get rid of these people?

Found it. Settings > Facebook > Contacts --- turn off. Now I can delete. I thought it had something to do with Facebook. It must have been an insipid update.
