How to change Sun Height value?

Hi. I can’t change Sun Height value in Override Settings when i choose Sky Sphere in World Outliner. Default value is 0.348239. Unreal Engine version is 4.21.2.

can you provide a bit more information? screenshot or what exactly you do are you trying to change it while playing?
For me, it works fine when I change the settings in the editor.

Under refresh material, you can see there is a light source linked to it. If you want to change it just click the little golden arrow beside the dropdown.
Hope this helps!
