Help Contacts won't display in Email on phone

[Palarin]

I have an LG Optimus g Pro (e980). I have several contacts in my contacts book on the phone but whenever I try to create a new email, the contacts do not come up for me to select one.

I tried creating 2 new contacts but only those 2 contacts appear when I click on "To:" in a new email message. I'm using a GMail account.

How can I get this resolved?

Thanks,
Marie
