The Pinnacle of Flame bug (not awarding points)

I am stuck at 8/10 boss atlas skill points. I think I found out why. I already received the 8 points from the increasing map difficulties.

The last two points come from The Pinnacle of Flame quest. I could not find the Stone Citadel so I purchased the key from the currency vendor. I went and killed Arbiter. The quest is showing complete in my quest log within the map atlas but it is still "lit up with color" instead of grayed out like the others.

The bug stems from killing the Arbiter without collecting all of the citadel stones within your own map atlas first.

did you find a fix ? i have the same problem
