Not Happy with the Computer Simulation for my Invisalign Treatment, but the Doc Doesnt Change It? (photo)

Starting my invisalign treatment in a few weeks.During the consultation phase, I told the doctor that I needed to see how my teeth are going to turn out, so I can be confident during the process. When the images came in, I wasn't happy since he didn't address the straightening of the upper front teeth. So, I told him to change it & he just doesn't do it. He says he has ordered it and cannot do anything about it; says maybe we can make refinements. I am feeling every unsure; should I go thru' this ?
