Problem with a 3 month game pass ultimate card

I had 17 days left of game pass ultimate I decided to buy a 12 month Xbox live Gold card and a 3-month game pass ultimate card put in the 12 months first then the 3 months game pass ultimate card so that the 12 months would convert to game pass ultimate as well. Instead it only gave me 8 months game pass ultimate total as stated above.

You can't convert it to Game Pass directly.

If you however have an active Game Pass ULTIMATE subscription (that combines Gold and Game Pass), the Gold membership card will add time to your Ultimate Membership.

However, since ULTIMATE combines two subscriptions, you won't get the full 3 months from the "Gold only" membership card.

According to the
Game Pass ULTIMATE FAQ page you will get 50 days of Game Pass ULTIMATE added to your subscription with a 3 month Gold prepaid card.

When you buy more Game Pass Ultimate via on the store or with a gift card, it will extend the length of your Ultimate membership. It will inform you when it will expire as well. Another cool thing people don't often know is that if you have a 3-month regular
Game Pass redeemable code and you currently have an Ultimate membership, it will convert the 3-month Game Pass into 2 months of Ultimate membership.

If you add another gold card or game pass card while you have Ultimate, it will be converted to Ultimate, but at a different conversion rate.

It would convert the remaining Game Pass Core to Ultimate at a ratio of 3:2.

That would be a problem because i didnt redeem my game pass core with a gift card. My dad pays it automatically every month.
