Mine craft realms plus

I bought the minecraft realms plus yesterday on the nintendo switch and I'm not able to acess the 50 + marketplace packs however i did get acess to own personal realm. When i go into my settings on minecraft and into subscriptions it does say that i have it and that i have 28 days remaining, and at the bottom of it reads extend ot info and when i click on info its telling me to buy it again Why can't i cant i acess the worlds for free that come with sunscription
