I bought a customization pack on the 360 that I cant use on the Xbox One

Hey, so I got the steampunk exo pack on the 360, and now that I switched over to the xbox one I cant use it. I downloaded it for "free" over the xbox one dashboard -as it should be- but when I try to select it, it takes me back to the store and when I try
to get it again at the store It says that I already have so I'm lost here

:)

 

Purchased Add-ons not transferring

I have COD:Ghost for both the 360 and the Xbox One...I made a few purchases on the Xbox one that are not reflecting on the 360. I purchased customization packs on the Xbox one but can't access them on the 360. Does anyone else have this issue? How can I
fix this?
