360 GOTY add-on disc and XB1 backwards compatibility

I installed Borderlands 2 (360 version) through inserting the add-on disc from the GOTY edition. It installed, through backwards compatibility, the main game plus all the associated DLC onto my Xbox One hard drive, and are all visible in the “manage game” section. When I load the game, however, there’s no option to load the DLC and any attempt to access the content results in a pop up to pay for it. I’ve tried reinstalling, hard reset, clearing the cache… Nothing. Any help?

The only thing I can think of to try is to install the content onto my 360… then load up the BC XB1 version and see if that “authenticates” it there (since playing a 360 game on One basically logs you in to a separate “console”)? No idea.
