Endgame, map and boss problems

Hi, I have a few problems on PS5 with POE2.

1. i have finished the campaign and can play the waystones. However, the endgame is not shown on the map.

2. in act 1 the final quest is open to travel to act 2. However, this cannot be completed either.

3. in act 3 (normal), only 4 waypoints are displayed as of today.

4. In Act 3 (Cruel), there are bosses active on the map that have already been completed several times.

I have already reinstalled the game and cleared the console cache. Unfortunately nothing helped.

How can the problems be solved?
