Every time I hit an automatic save it says that I am out of data storage xbox one

After the most recent October 2022 update, I have started to get a message everytime I hit an automatic save - That I am out of data storage space. I have plenty of storage on my xbox one and the world I am playing is the only one I have saved on Minecraft. It is also the only thing I play with my mum as we are currently living in different countries, and it is something we are able to enjoy together. What is the problem? Is this a bug? Because my world is 1.3GB and that's not very big.
