Are you referring to the "doubled contacts" as in their names are doubled or their name and number? Google tends to keep data around for all you communicate with. The ones not in the contact list are treated as one with an ID of "0". I filter them out by that ID. GV might have changed, breaking this (again, Google rolls out updates gradually so it could be a while before I see this issue). Once we get a better picture on the other issue in case they are related, I could add a filter for blank names.
