Then that means you already gave her the human kit.
what is your current friendship points with her?
if you saw the Android with black hair(Human Kit) and you still have that message popping up then you do have a bug, since Black Hair Android scene goes first than all the scenes you have just mentioned.
You can buy the human kit after she gets rejected from a Restaurant because she is an Android(Sex Doll), after that you can give her the Human Kit and then the scene of them going back to the restaurant begins.
