How can I resolve the message 'screen overlay detected in my galaxy s6

[AC Question]

whenever I try to access some apps on my phone, I am advised that screen overlay has been detected so I am advised to go to settings and turn of screen overlay. However I cannot find screen overlay in settings menu

Settings... Application manager.... More.... Apps that can appear over.....
It's an irritating glitch with these phones or maybe a marshmallow feature...
