Probably a simple solution.

When I go into messaging, and start to type a person's name, numerous email addresses pop up to. How do I unsync/get rid of theses, so that only the name/phone numbers show up?

Ta in advance

 

Bog standard messaging that's already on the phone

 

Looking in Contacts shows only phone numbers anyway.

When I type a name into "Enter recipient" it starts to find a name. If I scroll down, email addresses appear as well as the person's phone number.
