Miles on AF codeshare flights

Evening all,
This is probably much more trouble than its worth, but here goes. Through a work flight booking tool, I'm off to Zagreb next week with a stop, booked through Air France, but codeshares also with VS numbers.
BE3121 (booked as AF5023) and OU471 (booked as AF5074). The first flight is also VS8360, so I thought I'd be able to claim the few miles available, but the AF booking site, when entering my Flying Club number, just refreshes without having added it (no error is shown).
It also seems that the sale took place in Spain, as I'm actively redirected to the airfrance.es site to enter my details (or try to, in the case of the Flying Club number).
Is it even possible to claim the miles on this flight or am I just better off leaving the details blank and then reclaiming the miles (150 I think!!) retrospectively?
