"World" section of the menu vanished

This is driving me crazy.

Since yesterday, my menu is messed up.

It is now fullscreen while it was on a black background.

And the worst, the "world" section simply vanished...

That means, no more access to the "World" subsections "Realism", "Time & Season", "Weather"

Fortunately, I can still access these sections from the main screen.

But... I mean... WTH ???

Did any of you, by any chance, already experience this issue ?

Thanks
