How do I get the collision to work on a rain Niagara particle system

Hello, I am struggling with my rain particle system (GPU) that is facing into everything even though I have a collision component on it. I’ve looked up and read many people struggling with this same issue, however whenever I try it seems to still not work.
heres my system

Heres my world ( i do have a dust particle but that needs to be everywhere so I’m not too worried about that system)
