It's also possible that Cinder's Grimm arm isn't really hers but instead it belongs to the Grimm inside her, that she has a connection to but in the end is still a separate being.

When you look at it that way, it's easy to explain why Cinder's Aura wouldn't protect the Beetlejuice inside her, nor the Grimm arm it grants Ciner.
