Hi There,

When you convert to Game Pass Ultimate it automatically upgrades your existing Gold membership as is mentioned in the official rules. Therefore in your case my advice would be to contact Xbox Support and explain to them your situation and see if they can
help restore your Gold subscription.

Did a bit more digging in the FAQs, no issues at all for existing Game Pass members (direct quote from FAQ):

If you're already an Xbox Live Gold or Xbox Game Pass member, any days remaining in your membership(s) will be converted to Xbox Game Pass Ultimate at a conversion ratio when you redeem the 24-month Xbox Game Pass Ultimate
membership and added to your Ultimate membership up to a maximum of 36 months. Xbox Game Pass Ultimate memberships are limited to 36 months.

If you’re already an Xbox Game Pass Ultimate member, wait until your existing membership has a prepaid balance that is less than 12 months before redeeming the 24-month Xbox Game Pass Ultimate membership through Xbox All
Access. You will be unable to redeem with more than 12 prepaid months of Xbox Game Pass Ultimate.

To check your prepaid balance, go to https://account.microsoft.com/services. Note, once converted to Xbox Game Pass Ultimate, Xbox Live
Gold and other Game Pass memberships cannot be unconverted. Learn more at www.xbox.com/gamepass.

Yes, you can cancel Xbox Live Ultimate whenever and revert to only Xbox Live Gold.

So, when it says "Purchase of Xbox Game Pass Ultimate automatically upgrades your existing Xbox Live Gold or Xbox Game Pass membership(s) to Xbox Game Pass Ultimate at a conversion ratio each based on days remaining. Future
code redemptions are also subject to a conversion ratio. Conversion ratio subject to change. All conversions to Xbox Game Pass Ultimate are final: Once converted, you cannot re-convert your Xbox Game Pass Ultimate membership back to a previous membership.",
it means if you activate Xbox Live Gold subscription when your subscription of Ultimate is still active. ¿Am I right?

I think after activating ultimate, if you redeem a Xbox live Gold, it will extend your ultimate subscription.
