I think it may be that the contact is saved to both the phone and your Google account. If you click on a each of the same contact and look at where it says 'account', one may have the Google logo and one may have a mobile phone icon.
You can join contacts though. If you click on a contact that is duplicated, then click the 3 dot menu button top right, you should have an option to 'join'. Click that, and more often than not it should suggest the correct contact to join with (which would be the duplicate). Then when you look in the 'account' section of that contact, it should have both the Google logo and mobile phone icon. You then should end up with only one entry in your contacts list for that particular contact.
I'm not sure if there is an option somewhere to 'join all' duplicates, which would make the process easier.
I've had this issue before and that's what I did. Someone may have a better way of resolving the problem.
