"The Collector" quest Elwynn Forest

Hi,

Level 38 Death Knight here leveling in Elwynn. I see the “The Collector” quest available on my map. However, when I kill the NPC that drops the item - James Clark - he does not have it on his person. Is this because I am Death Knight? It reminds of the quest in the starting zones that doesn’t show up for Monks.

Just asking here to see if there’s something I’m missing. Not going to waste a GM’s time with this. lol

Thanks
