@GeetaSarvadnya I think this might be wontfix, seems like proper behavior.

Per your steps to reproduce, if a user is going back to customize sync it doesn't necessarily mean we should go back to the default settings of customize sync. As a user, if I selected sync everything and went back to customize sync, at the customize sync screen is where I'd want to now be able to unselect the items I don't want.

@karenkliu Can you take a look? My comment make sense or disagree?
