Go to "Settings > Switching Desktops" and disable the option "Customize desktop icons".

I restarted my computer and i noticed that all my desktop icons and folders only showed up on desktop 1, so I transferred them to all the other desktops. Now, whenever i save something on desktop 1 in one of my folders, it doesn't show up in the other desktops. Is this a bug? If yes how can i fix it? If no, how can I make all my desktop icons and folders be the same always (synced)?
