Wallpaper

So I tried adding 2 different live wallpapers on my phone using tiktok, one for my lock screen and one for my home screen. Problem is, it doesn't seem to matter which screen I set it to as they don't don't separate. The wallpaper I set to my Lock screen will also be the one set on my home screen,even if I already set a different wallpaper on the home screen. Is this just how this works?
