Settings app not showing in System Components

Hi All,
here is something out of curiosity and not an urgent cry for help.
Why can I right click on my Settings icon and go into the settings of "Settings app - in system components ... but ...
when I open "settings" normally and go system > system components .. there are 4 components (e.g. Get Help, Store, etc.) but NOT an option for entering the settings of system components. ??? ... nor is the Settings" app listed there, as the other 4 are.
The reason I encountered this is that I always see a spinning blue circle when opening "Settings" app for a few seconds (not on my other machine)
and I wanted to fix it.
So, from right-click on Settings icon I can enter the system components settings and chose "Repair", etc.
But why is there no settings option when entering the exact same location - system components - ??

Thanks
