certain Minecraft realm minigames wont load and I cant load them by uploading a world

I have bought a realm for 180 days almost exclusively to play realm mini-games and I haven't been able to play some of our faves or try some interesting new ones from the last we played. I've tried every day since I bought the realm and would just like access to all of the games I paid almost $50 for and to be able to upload worlds of my choice. please see this and help me out thank you for your time. some of the games I want to play are the pixel parties and short fuse.
