My Laser particle is invisible in splitscreen

Hi, i’ve a problem with my laser particle system in splitscreen. As you can see in the image, the laser is invisble for the first player while for the second player the laser appears normally. I tried to play with one player and the laser is visible. I also tried to eject in splitscreen and he’s visible too, so the problem is caused by the splitscreen. I really don’t know where to look. Any ideas please?
