Really weird particle glitch on unity 2d

To be honest, im not sure if its a glitch or not, but its definetely weird.
Im using particles effect to make the rain on my game, but for some reason, when i walk with my character, the some of the rain particles go to below his feet, VERY below his feet, but sometimes aligned to him, its hard to see it, but if you pay atention you can see what im talking about
look to the left of the moon.

By the way, it only works when the splash is turned on, without it, it works normally (splash is another particle system, but this one is for making an "animation" when the rain collides with something, i cant put it off, i really need this thing happening)

really need some help here guys, any guesses?

 

Anyone??
