This is a Save File issue. All game data, including world saves, skins and skin downloads, world downloads, and resource packs are using the same "Game Data Save File" on the Nintendo Switch, which has a maximum file size of 2GB. Upon loading the file, the Switch has unpack it to load the contents. The game is not probably deleting any information in "Game Data Save File." I would recommend fixing this issue, or limiting local world generation size to legacy world sizes only and only allow infinite world generation to Realms only. Or try to find a way to work with Nintendo to remedy the file size issue
