I'm starting from a referenced library and I don't want to export the masters. 

I would have expected to retrieve a Group/Project/All images structure, as in C1 built-in importer, to mimic my Aperture Folder/Project structure,

and :

1) I get a Group/Albums structure. Whatever the option chosen in "exported library structure" 

2) the initial order of projects inside Aperture is not respected (I have hundreds of them, this makes it very complicated to reorganize) 

Is it a bug ?
