Unable to unlock achievements or open marketplace rewards

I am currently unable to unlock the following achievements:

Endurance DLC - One way to do it, Who needs a map?

Baba Yaga DLC - Persuasive argument

I have followed the steps found in previous threads about this issue and have not had success. I have even removed my account from my Xbox One, restarted the system and re-logged into my account. I then performed the steps in game needed to unlock the achievements
and still had no success.

I also have a number of card packs pending in my markeplace tab however each time I try to open them I am told they have already been redeemed. This is unlikely as I do not have access to the Endurance mode-specific cards that were meant to have come with
the DLC. Nor do I have the Anniversary skins that were meant to have come with the Tomb Raider 20 DLC.

My system is an Xbox One, Xbox Live Gold account, all DLC purchased separately.
