I’m not sure why your anchor point is defaulting to [0,0,0] instead of the layer center, when I import my anchor point defaults to the layer center. So I can’t help you with that. But, there is a “name your price” script from AEScripts.com that repositions the anchor point of layer that you might find handy.
