So I am understanding this correct. You are seeing the T/D after the waypoint with the altitude constraint?

What STAR for which airport and runway. If you want, I can try the route myself and see if it happens to me. So far, I have not done a flight where it didn't follow the constraint altitude(s) that are included in the STAR (from the AIRAC) itself. Also. Which AIRAC are you using, the default 1207 that comes with the 777, or an updated AIRAC from Navigraph (latest is 1407)?
