Particle system ends with shuriken graphic

I’m testing my particle effects in the unity editor player. I have a non-looping particle system, and when the effect ends it leaves a billboard type graphic of 6 shurikens just statically hanging there.

Is this normal, and how can I get rid of it?

This is called a gizmo. Its just there to let you know there is a particle effect present. You can see the same thing on lights. It doesn’t turn up in the final build.

This page in the documentation tells you how to turn gizmos off
