Bug in “Trail of the Sekhemas” - PO2

I have a bug in “Trail of the Sekhemas”. I completed the map and killed the Boss on the second difficulty, but for me only the map on the first difficulty is related. If I teleport to the map, I am sent to normal difficulty and level 22 monsters.
I tried to redo it several times and it didn't work, I also tried to enter another user's session to see if it would correct the quest, but I enter the map and I can't add the currency.
