contact help

[stock28]

Under my contacts I have phone contacts and Google contacts as well as several I created such as family and coworkers. I don't recall having the phone contacts and the Google contacts before as they are both the same. The problem comes in when I try to add something like a birthdate to a contact. It shows up twice as it lists it in the phone contacts and Google contacts. Why do I have both and the phone and Google contacts lists and is there a way around this so as not to have multiple entries?
