S7 edge notification popup UI change

[Aresh]

For the past couple of days, the UI of the notification popup has been changed on my Oreo s7 edge. It has now been reverted to the way it was on marshmallow. Posting some photos for better understanding. 

The screenshot of twitter is the one which I used to get. The one with the files is the one which I'm currently getting.

Hey Shermi. I fixed the bug. Just go to settings>general management > reset > reset default settings
