NotifyActorOnClicked not working

NotifyActorOnClicked does not work. Instead I’m getting:

1) mouse-over triggers NotifyActorBeginCursorOver

2) mouse-click triggers NotifyActorEndCursorOver then NotifyActorBeginCursorOver

In my player controller BP → Mouse Interface, I enabled Enable Click Events, Enable Touch Events, Enable Mouse Over Events, Enable Touch Over Events.

project settings → input → use mouse for touch was checked (should be unchecked)

This solved my problem. I hope it helps someone else.
