I can't download Minecraft Mini games/world's I've purchased.

 Hi I've spent money in the Minecraft store on worlds and mini games, but when I try to download them it says I don't have enough space on my PS4, however I've checked my storage and I have over 300gb free and on my Minecraft app I have full storage free. I would like to get these games downloaded please. My issue is the same as this person describes in the screenshot below.
