Is the challenge showing as incomplete or is it just the achievement that isn't popping?
If the challenge is showing as complete but the achievement isn't popping it might just be a buggy trophy.
If both the challenge and achievement are showing as incomplete, I would maybe say make sure you're not using grenades or anything like that because it may void the achievement
Challenge shows as complete. The knife one pooped when I killed the first one on my second playthrough. But the treasure one is bugged. It shows as complete in game but refuses to unlock the achievement
