Light visualization in the editor problem

I was looking at the “Intro to cascade” videos on the unreal youtube channel, and when I tried adding the light module to my particles, nothing changed in the editor. I tried ramping up the intensity values of the light to values up to 300, but still nothing. Yet, when I launched the game, the light was there. I don’t know if I accidentally changed a setting of the editor or if it is some other kind of error.

The same problem occurs with the volumetric scattering intensity, visible in the launch, but nothing on the editor.
