How To Group Notes On Notification-bar?

Aug 21, 2016
I have setting up my new Redmi3S (with 7.3.2).
And after installed some apps, i recognized that the notes from PlayStore (app XXX is installed) aren´t in group like it was on my redmi2 before.
so every "app XXX is installed" note is separate shown on one line.
means i have now 3-5 line with notifications only from playstore, but before it was in group and only 1 line.
Is there a setting for this?
