Not able to edit/delete a contact from icloud
I have few contacts in my icloud which i am not able to delete or edit. These contacts were previously deleted manually from my iphone. But when I login to icloud, i can still see those contacts. When I try to rename or edit these contacts, it says "Couldn't save the changes to XXXX". Your changes to the contact couldn't be saved because it was just updated by another device. I am sure I am not saving my contacts in any other devices other than my personal iphone. Can anyone suggest any options?
Thank you,
