Backwards Compatibility broken once again.

Ok, has anyone the problem that pretty much all goty etc editions of 360 games dont work anymore?

Pretty much all games that include dlc on disc refuse to work on my XBOX ONE X correctly (Battlefield 3 Premium Collection works for some reason). All those games show me is this message: Theres a problem getting this content right now. I can still download
all the dlcs+ game through the shop (while the disc is inserted) and even start from disc after the download is finished (the Theres a problem message goes away after the download and the game cover appears). Except one game. Dark Souls - Prepare to die Edition
does not exist in the shop anymore, so its permanently unplayable on my XBOX ONE. Is there any known fixes for this? Because google says that im the only person on our planet that has this problem. And please dont tell me stories about the usual all around
fixes for everything. Theres clearly something fundamentally broken and resetting the console/router or factory resetting didnt help. My nat is open and i tried lan/wlan.

Clearing blue ray cache and redownloading my profiles didnt do anything either. Im also pretty sure that it wasnt actually the series x shop update that caused this. The last time i tried to install Fable 2 and Assassins creed 2 a few months ago i noticed
this problem for the first time and thought it was just a weird glitch that happened that day. These 2 games were always weird on my console, for a long time Assassins creed 2 just kept on downloading Fable 2 and i basically couldnt play Assassins Creed 2
for a year or so. Now im trying to install all my bc games on one hd for next gen and only one single game with dlc on disc behaves like it should.

Manually downloading also doesnt fix anything, as soon as i delete the content everything goes back to 0 and i have to manually download everything one by one from the shop again. Another weird problem that i noticed that wasnt there before is the duplication
of certain dlcs. For example some games have the english voice over as dlc in europe if you had a version that didnt have it because of the storage issues on xbox discs. I noticed that one of my games (assassins creed 3?) had 4 different licenses of the same
voice over patch and downloaded all of them after pressing the ..Install all.. button under My games & apps. Some other games also wasted several gigs of space because of this.

Theres more problems i found over the last 2 days but these 2 things are unacceptable for me, straight up unplayable games and huge amounts of useless duplicat downloads that waste space on my hdd and bandwith.

I installed over 100 games over the last 2 games and all other games download normal except the duplicat dlcs on some.

The last things i tried were using one of my other 3 accounts and also changing the region/language of the system.
