No "Settings > Background" option in ElementaryOS

[tGmn]

I don't have any experience with Linux, but I started using ElementaryOS and wanted to use these Dynamic Wallpapers, I managed to install it and everything went successfully until I noticed that there are no "Background" options in the Settings window. There's a wallpaper settings, but it only shows the default wallpapers. There's an "import" button, but that's just a regular image import function.

Maybe I'm being silly due to my inexperience, but can someone help me?
