[MCPE-176166] Lighting Issue

For some reason lighting is completely messed up for me.

It's hard to explain, but basically, during the day, around sunset, it flicks over to a night lighting. Like it goes from light level of the day straight to light level of night in an instant. And the same in the morning. Sometimes, and I haven't been able to steadily reproduce this, it will remain 'dark' even though it's supposed to be day. Entities appear to be unaffected by this, being in fullbright.

Steps to Reproduce:

Open a world
Wait for day cycle to pass to night
The light will flicker from light to dark strangely
Do /time set day and generally it will keep a darkened effect over the environment.

Sorry if the steps aren't helpful enough, or if I am unclear. It's hard for me to explain.

Extra notes:

Fancy Graphics is: ON

Smooth Lighting is: ON

Beautiful Skies is: ON

I had a resource pack enabled during the screenshot, but effect was identical without any.
