Water particle shading issue

Hello everyone!
I bought water particle on marketplace and it doesn’t look like it should (i.e. like on screenshots and vids from seller) - the water looks dark in my UE 4.25.3 instead of being clear and transparent. Screnshot inlcuded.

I’ve already sent question to seller, just have no idea when he will respond (if he will at all).

And unfortunatly there is very little I know about particles at all.

The water material itself looks clean and transparent and rendering fine. So probably its something wrong with particle? Also on sellers’ screenshots everything is fine, so probably its something that been changed in Unreal lately… just guessing.

If someone got any idea what is this, and how to fix this, it will be very appreciated.
Cheers and thanks for reading!
