It's a bug. The original version of this content used a golem but we later reframed it with a different character so that it was more inline with established lore, etc. This NPC string got missed during the review pass.
A fix has been implemented but it won't go live for a few weeks.

What you're talking about is a different bug than the one the OP mentioned but I thank you for bringing up that one too!
Hello, just a heads up this should be fixed on Live now! (:
