Contact listed twice when not in contacts.

I used to have a contact I named Facebook in my contacts with the Facebook number so I could text status updates when I was out of wifi range. So on my phone when I go to start a new text I type Facebook in the recipient field but two contacts are coming up with similar but not the same number. One is the one I added and the other one say "other". Since then I have delete Facebook contact from my phone but it still shows up 2 Facebook contacts (when I type Facebook in recipient of text message) now both showing "other". How do I get rid of these when they aren't even listed in my regular contacts anymore?
