I have an issue with the campaign quest where I am supposed to find boots with the main attribute att% in Arnoc level 6. I tried to complete the quest multiple times, I found proper boots but the quest just does not complete. 

I am playing on an iPhone 8, iOS 13.3.. 

I tried to relaunch the game several time and tried to complete the quest on normal and hard mode, there just seems to be no progress. 

I would very much appreciate assistance!
