World not exporting corectly

Whenever I export my world to move it between my laptops, none of the data is exported. Even when I tried moving the world file itself, all the data was deleted, and when I opened it up it was like playing a new world on the same seed 

*edit I have now tried to upload it to realms and attempted to export other worlds all they all fail. It continues to say that the import failed when I try to import them to mc
