my water graphic has changed after importing assets,My LightWeight RP water graphic changed after importing assets

I used LightWeight RP to make water graphics. I made PBR shader-based water materials and applied it. It seemed great at first, but after importing unity’s particle pack from asset store, the graphic has changed, and material icon got weird too.
Is this the problem caused by some settings in imported assets? I tried resetting player settings but no changes. I have totally no idea about such settings.
please help;;,I used LightWeight Render Pipeline to make water graphic, and made a PBR shader-based water material. The graphic seemed great at first. But after importing Unity’s particle pack from asset store, The graphic has changed, and my material icon seems weird too.
I reset almost all settings at player settings but no changes.
Is the graphic setting wrong? I have totally no idea about such settings.
Plz help;;
