Windows 10 Changing System Language

Hello Community Members,

I’m trying to change the display language of system. While I’m about to do that by following the instructions on web, something unexpected for me happens. For almost all the walkthroughs on the web, there is at least a mark which indicates a display language pack available at the page of preferred language selection but for me there isn’t.
Here is the image of what I’m seeing and Here is what it actually needs to be .

So I can’t install the pack as a display language. Where am I wrong?
