How to delete extra contacts on Samsung Galaxy S4 Messaging?

[Nick]

I recently went through my Samsung Galaxy S4's contacts to get rid of any duplicates that came up because of my synced accounts. I cleaned it up and turned off syncing for my contacts from accounts like Google and Facebook, but whenever I click the contacts button in my messages to add a contact, new contacts show up on the list. It suddenly shows contacts that are just email addresses (that I recognize as people I have emailed from Google before), and some duplicate my contacts. However, when it duplicates, one of the contacts has the phone number I want to text, while the other is just an email address. The problem is that I can't tell which is which, and I don't want the emails in that contact list at all. I un-synced all my contacts from Google, so I don't know how these emails are showing up only in the messaging contacts. Please help me!
