Halo Wars 2 Digital Pre-order Bonus Pack issue

l just pre-ordered Halo Wars 2: Ultimate Edition from the Xbox One Store, but when I try to download the Halo Wars 2 Digital Pre-order Bonus Pack for Halo 5 it says “Not available” How can I fix this? Or is that not available for the Ultimate Edition?

You’ll probably have to wait till the the full game comes out … LOL.
