Lock screen is not changing after updating to Android 4.4.2

I have updated my Samsung Galaxy Grand 2 to 4.4.2 and after that I'm not able to change my lock screen wallpaper. It always shows a wallpaper which is already in the device which has red background. Home screen changes every time whenever I want to change but lock screen remains the same. But if I put a live wallpaper as my home and lock screen it applies to both home and lock screen. Please suggest something how I would be able to put any pic from my gallery as lock screen. I changed the lock screen through settings also but no use.
