My contacts address book is maxing out independently

[DMP107]

A few months ago I unlinked my contacts to try and correct some information in one of them. I could not re-link them and eventually my address book froze up. I deleted it and started over but just these past few weeks it has been filling up spontaneously with all kinds of old emails and contact names and I'm having to delete them all over again. Any clue as to how to make this stop?

Hi and welcome to Android Central.

Is this syncing with gmail contacts?
