"screen lock" isn't accessible in developer options..

[JohnnyKarate01]

I'm trying to get rid of the screen lock on my Honor 6x running 7.0 but when i go to developer options it's grayed out so i can't disable it. I can disable the pin or pattern but i just don't want to swipe the screen every time i wake up my phone.

Any idea how to fix this ?

Thanks.
