So i completed the Black Talon catalyst, equipped it on the sword and when I check the Triumph (Account>Exotic Catalysts>Power Weapons) it only shows 8% enemies defeated. I also have 2 Worldline Zero catalyst triumphs for whatever reason. Double points is cool though.

These are known issues. The Black Talon catalyst Triumph will complete when you finish the Triumph for the Lord of Wolves catalyst.
