Can't Increase Collision Shapes of Particle Collision

Hi everyone.

I’m having a problem with my particle trail. It has very little amount of collision shapes and I could not increase the number no matter what I did.

Changing “Max Collision Shapes” doesn’t seem to make any difference.

I highly need your advise.

Whenever I decide to ask a question publicly, the answer comes in two minutes after. lol

Here’s how I increased the amount of collisions:

I simply increased “Rate over Time” from 25 to 100. It has affected the visual but I guess it’s okay.
