To use orientation control for the drone, you will have to change the flag controlModePosVsOrient to 0 from 1. In the controller that is used by the drone, you can either work with Position Control or Orientation Control; not both together. The Yaw control is working since yaw has an independent controller in position and orientation control.
Everytime you type the command parrotMinidroneCompetitionStart, a new Simulink Project is created. When the new project gets created, you can go to the folder one level above, and access all the projects that you have created typing the command. You will see multiple folders with parrotMinidroneCompetitionXX name; where XX is a number.
Maybe you can keep the folder you are working on in a different directory or just remember the number of the folder.
I hope this helps!
