Windows 10: Night Light sunrise time incorrect

Hello. I use the scheduled Night Light feature on Windows 10 and the sunset time is correct for my location, but not the sunrise time. I have my PC set to UTC/GMT permanently. If I set it to the London time zone, the sunrise and sunset time are both correct. I had thought maybe it was set by time zone and it was using an equatorial location, but as I say, sunset time is exactly right for my precise location even on the UTC time zone. I have set my default location correctly and I’ve tried clearing it, disabling/enabling it, restarting, switching Night Light scheduling on/off.

Windows 10 Night Light on after sunrise

Well, I ended up going to the Night Light settings and selecting "Set hours", instead of "Sunset to sunrise", that immediately turned off the Night Light filtering. Then I just re-selected my original "Sunset to sunrise" schedule setting and the filtering remained off, as it should be, and the setting is indicating "Off until sunset" now. I haven't checked to see if this is included in @dalchina suggestions, thank you for those.

I'm not sure what caused the weirdness, we'll see if it comes back. Recently I did play with the Night Light "Strength" setting, so maybe I inadvertently did something then.

 

Windows 10 Night Light on after sunrise

I just noticed this morning that Night Light is still on after sunrise. The settings indicate "on until sunrise (7:25 AM)" and it's 10:22 AM. I use the "sunset to sunrise" schedule. Rebooting doesn't fix it. Any ideas?

 

Windows 10 (1803) Night Light Sunset/Sunrise time incorrect

The Sunset/Sunrise setting in my Night Light feature is incorrect (see attached screenshot). I've read several other posts on the topic and tried out many recommendations with no success; among them...

a) Clean boot

b) Deleting respective registry data (HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$$windows.data.bluelightreduction.settings\Current)
