Copyright not populated when loading to Local Files

I can't speak for Adobe, but personally what you describe is expected behaviour. Technically, when you load images in the Local mode from a memory card you are not importing them, you are simply "saving" them, i.e. copying them from card to disk. Import actions, such as adding copyright or using non-default develop settings (i.e. Camera Settings) would not be applied in Local mode. However, I would expect them to be applied if you then choose to copy a local image to the cloud....and in fact that is what happens.
