Default Can't change lock screen wallpaper

Hello All,

Strange problem, all of a sudden no matter what I try u can't change the lock screen wallpaper. Trying from gallery doesn't work, neither does trying from that lock screen settings. It worked fine about a week ago and when I try it tells me it saved/applied but never changes. I tried going back to stock launcher from Nova just to make sure that wasn't the issue but it had no effect. Any ideas?
