How do I customize my Lock screen?

Lock screen problems

I'm trying to customize my lock screen, but for some reason I do not have any options to do so... All I get when I open the Lock Screen option is "S View window Color" and "weather unit" while in the tutorials I see there are many other options like "Dual clock" and many more. What should I do? I've been looking in tutorials and everything but cannot find the solution. Is my phone wrong??
