Xbox All Access and Game Pass

I bought an Xbox One S with All Access a few months ago. Recently, on the Microsoft website, I was trying to pay ahead on my All Access subscription but it actually set up a whole new subscription to Game Pass Ultimate. Now I'm paying $25/month for my original
All Access Game Pass, and a second $15 a month for a different Game Pass, I guess? If I cancel the new subscription, will it also get rid of the Game Pass subscription that came with my Xbox?

I really don't know what to do here, and I can't get through to talk to a human on Microsoft's end. Any help is greatly appreciated. Thanks!
