Mysterious plane created on enabling particle collision

Hi, i have been making a game that has a particle system. However, when i enable collisions on the particle system, it creates a mysterious plane and the only way to get rid of it is disabling collisions again. Does anyone know what this is?

Any help is greatly appreciated, thanks.

Well first of all as you can see on the Inspector, you are creating a plane when adding collision,

I have not seen this happen before but I have seen something similar in my work once,

On my work all that happen was I got the plane but the plane was gray,

From my experience just changing the visualizations from solid to grid should work,

Let me know if the problem persists,

Good luck,
