F3 Feature NOT Available

I cannot access the Debug information section. F3 does not open it. My F3 button works. FN+F3 as well as ALT+F3 do not do anything

My settings does not show any option about the debug information overlay.
Ive installed and reinstalled java and minecraft several times.

 

what do i need to do in order to see my coordinates? (Windows, Desktop, Java)
