Unfortunately. Captain Sim sell only the download version here in their online store.
Just Flight, on the other hand, repackage the CS to their own liking, and sell it in a box.
I assume that CS must get a percentage of the sales. So if you buy a box product from Just Flight, it is not really Captain Sim's fault that if Just Flight leave out models or liveries. It is the way Just Flight want to do it.
Captain Sim would prefer everyone to buy directly from their store, here, as it means more money for them (I assume), because you cut out "the middle man".

I was lucky that I bought download versions of CS products (from another reseller), but since I found out that CS sell it themselves, I buy from the online store here.
