Though I have more than enough storage my minecraft will not let me preform certian functions because it keeps saying I have to little storage

I am on bedrock and I was playing a mod with my friend then it kicked us off because we didnt have enough storage but I do I have 4 worlds and no packs at all. I have enough space on my console and on the game itself every time i try to download the realm or when I try to stay in a world past auto save it tells me to clear storage. On the console itself I have more than enough storage but on minecraft Itself I have 11.2MB from the server packs and 520.5MB from the 3 worlds I have. in addition to this my storage bar is hardly quarter of the way full
