Warden skin, please help

[Dark_One]

I made a skin for the warden model that removed her cape and made the two wing things on her back much smaller (I even managed to get rid of the two black things that you only see if the cape is gone). It worked fine in WC3 Viewer but when I put it in the editor, the cape and wing things reappeared.
Can someone please tell me why this is doing this or at least how to stop it?
