I finished the mission, but it doesn't update.

My missions are bugged; I can't track any more missions and I'm stuck on the same one. When I complete it, the dialogue simply disappears, and every time I teleport or finish a challenge, it comes back and asks me to do everything again, but it doesn't solve anything. The mission is called "Tour 2 Fan of Maneuvers, the Impossibility Point". I've already completed it, and it doesn't register as done. How do I fix this? 

I play on PS5.
