I purchased five worlds in minecraft in total. I cannot access 4 of them but it says that I own them.

I purchased 5 worlds in Minecraft in total but I can only play on one of them which is sport resort. I can't play High School Buddies, High School, Pool Party, and Pajama Party. Every since I purchased them I was not able to play them. I still have all the skins that the games promised they would give me.Thank you and please resolve my problem. Also I don't know what realm platform I am on so I just guessed. I also guessed for the affects version
