[Q] Detailed Notification Problem

I know this is a silly question but I have tried to find a solution but failed.
First of all:
Android version:4.1.2
baseband version N7000XXLS0
Build Number N700JPLSB

I had the detailed notification working properly on my device but suddenly it stopped working and instead it is showing the old ordinary notification.(tested with gmail notifications)

Is there a way to re-enable it again?:confused:

Thank you in advanced.
