Note 3 Text Notifications on the Lock Screen after upgrade

[Hillstoby]

Hi

Since my Note 3 has had its software update i have noticed that any texts i receive do not light up on the Lock Screen when i receive them!

What do i need to do so this happens again. I have already been to the Text Settings and unchecked the Pop-up display box in Notifications and it still doesn't work!

Thanks
