Help Why does One contact appear in contacts list as an email?

[NOVAdroid2151]

Good evening everyone!
I just noticed kind of a bizzare occurance with my X.

All of my contacts (via phone or via facebook) are shown in my contacts by their full names. I have my contacts list filtered to show 'Phone Contacts' Only. I'm not sure if this matters, but I'm stock and non-rooted.

I have one contact that has a name listed and has a cell number, but is being listed by his Gmail Account. His contact information has 1 number, 3 emails but his gmail account has a lock next to his name while the others can be changed.

I'm trying to make it so his name appears normal (first/last) in the contacts screen.

Can anyone help? He is the only one to do this in my phone.

Thanks!!

Has anyone had an issue like this?

Could this be from a Facebook sync, or similar? You wouldn't be able to change those details.
