I looked at your project.
I too have had problems when trying to do multiple (more than 2) sequential machining processes while using "Rest Machining".
For starters, I believe you'll want to change your strategy away from "Adaptive" on your last operation. What I would do is simply machine the profiles, with maybe one or two roughing passes.
