Niagara's scratch pad doesn't seem to work in the level unlike the Niagara preview

I needed to do PBD Niagara for project, basing on this tutorial. But in the end, the same Niagara System in “Prewiew Niagara” and “Niagara in level” are different. Its look like as if the scratch pad responsible for the collision logic does not work at the level,
although scratch pad for collision is enabled.



I think so, because if turn off the scratch pad, then the Niagara preview becomes the same as on the level

Here’s the collision logic inside and the system does not show any errors


Enreal Engine version 5.3.2

I have absolutely no idea what the problem is, pls help
