MSFS 2020 Approach doesn't match approach plate

Yes the MSFS pic shows the wrong arrival, but I did rectify that after and still the same. I do better understand how the system works now, thanks. What I know , if I load a flight plan from navigraph then the MCDU shoes the right path to he approach. It still a bit confusing and don’t really understand why ASOBO set this up this way. All other sim works properly for approach and arrival.
But again what do I know!!
