In the current Table, there is a Malevolent trait that makes colonies immune to influence flipping. I can see the point, there ought to be some counter to overpowering influence. However, there is also a Benevolent trait that supposedly causes all colonies within your zone of control flip to your side. These two traits appear to be contradictory. In my games it appears the Malevolent trait trumps the Benevolent trait.
Because the contradiction is so clear I don't see how to resolve this, or what one ought to expect in game.
