Only half of purchases have been counted towards sale Reward Points

Using the link from the deals "Black Friday sales" and using the Store on the console, I purchased 3 games to be eligible for the: Spend at least $70.00 on games from that sale & receive 5000 reward points. It only counted $45.00 (instead of the $70) when
the total came to $80.00 +

The Reward points have not been added to the account because it's only counting half the purchase.

Recent previous purchases from the Xbox store using a web browser also haven't seemed to reward any points ( + 20 points for each game purchased as a Game Pass ultimate subscriber)
