Anuk-Ite is something new. Its rules were not established, but it was established that it started out noncorporeal. We've seen in the past that noncorporeals (like Oni) have varying degrees of trouble with Mountain Ash barriers.

What is also clear from the dialogue is that Anuk-Ite did not have the strengths or weaknesses of a supernatural until this incarnation, suggesting it was not "that kind" of supernatural prior.
