Maybe I'm misunderstanding you but the chainrings are mounted properly. Has to be the way it is to be flush with the ring mounting surface (other than the Stronglight stamp isn't in line up properly). The outer goes over the top of the crank arm and the inner ring goes under the bottom. If definitely see you you would use a spacer to create a triple.





As mentioned, the outer of the three large holes on the big ring is countersunk on the back. I can't figure out the purpose unless it's for a chain guard. If those extra large holes are there to save weight then why would you make them that big. Just looks awkward like that. But, that's also personal opinion. I like that you could make a decent compact double with a combination of rings but... those extra holes, ugh.
