setting someone else's xbox as the home xbox

My friend that i’m sharing games with bought the arena req bundle pack. His account got the armor and the req pack while for me it said the i had the req pack but it didn’t show up. the req pack has also disappeared off the req store for me. I was going to buy it but now i can’t.
i don’t really know what else to say other then its weird how i can’t buy the req now.

It’s a little weird how it works as the X1 store won’t let you buy it because it detects a bundle download on your console. You can still buy it yourself from the Xbox Store on OP, although the bundle downloads to your account on the X1 through sharing you still need your own bundle license.
