Not sure about your particular green potato bits, but the pigment that makes these sweet potatoes purple actually turns green under certain circumstances - for example, if you make a pie out of the potatoes and the other ingredients happen to have the right chemical properties. It looks funny, but it's 100% safe to eat.
i bought purple potatos once but they had white parts inside and when cooked green parts. i didn't eat them just to be safe.

They do leech green pigment when boiled. Not sure what was white but that colored it most likely.
