Help Not displayed in scene

I was able to eject a Particele using Solver and Emitter.

Now I want to eject more than one Particele, so I duplicate the Solver and Emitter.
The Particele is ejected, but not displayed in GameView, and not displayed in ScneView before duplication.

How do I get the Particele to show up in GameView and ScneView?
