Finished Guulrahn Slums but did not get the Aspect

Finished Guulrahn Slums but did not get the Aspect. If I check the codex the PIN aspect button is greyed out which I presume also shows that I have finished Guulrahn Slums.
I canyt get back into the slums to check if I missed anything.
How do I fix this and get the Aspect?


Edit:

Ok so I have finished this dungeon again and still didn’t get the aspect.
But when I double checked all my items in my stash I already had something with it, so I guess I must have had it from a random drop which would explain why it didn’t drop after the dungeon…
