Remove “Add On doesn’t need to be installed”?

I just bought the Lightfall DLC for Destiny 2. I have already followed the installation steps due to the known glitch but the DLC still will not launch.

I have tried clearing the local save, hard resetting, deleting my account from xbox, deleting whole game, only installing certain parts etc.

I see at the bottom of my manage add ons it has “More Add Ons” but these are listed as “Add Ons / Doesn’t need to be installed” and I cannot do anything with them. I suspect this is the issue. Do i just need to return the DLC or can it be saved? I am not sure what to do at this point.
