Windows 10: Lock screen reverts to old picture after reboot

Kinda having an odd issue. I use the windows spotlight to set my lock screen. So that it changes about once a day automatically. But when I reboot the computer, it reverts back to some old lock screen image I set manually a couple months ago. If I login to the PC and lock it again, then it will go back to the spotlight image. Not a huge deal, just thought this was odd.

Personalation

Hi! Is it possible to personalise the lock screen on Nokia Lumia 625, so it is on after I have viewed messages, emails,etc? I have picked a picture, and set it as my lock screen, but after 5 minutes the screen reverts to black,, with no sign of the picture
I set! Is it at all even possible to have a screensaver on a Windows phone?

 

Unable to change Lock screen picture(Windows 10)

I have seen a lot of people post about the issue of to being unable to change the lock screen picture in windows 10 but most are unable to even select the file, for me when I select the file, the file is chosen, and it goes to show
the small screen which should preview the lock screen, but it only shows that it is stuck loading, and if I do or click anything, it reverts to my old pictures

 

From what I've read about the lock screen it only changes the background when you lock the PC not when you restart/start the device. *Smile
