Back on Track Error - Pilatus PC-12

In all my career mode flights with the Pilatus PC-12 I get the ‘Back on Track’ error during cruise flight.
Why does this error occur?

Are you flying above FL190? If yes, please check this thread: PC12 Pressurization/Oxygen System Broken

Thanks! It solves the problem

I have the same “BACK ON TRACK” ISSUE. not related to oxygen or cabin enviroment. I have to give flying the PC12
