EEVEE Waterfall Shader - why is everything tiled?

Hi, following this tutorial, using Blender 4.0. I notice some things in this tutorial don’t exactly apply, such as the gradient UV map. That is, in the EEVEE Waterfall Shader that I bought here

the existing waterfalls only have one UV Map.

Also, after I select my added plane, then shift click one of the waterfalls and hit Ctrl L to copy modifiers and link materials, I see that in my added plane that I am using to create a waterfall, that the waterfall is tiled.

In the tutorial about this shader here

when he adds his plane and does the steps mentioned, I don’t see any tiling in his waterfall.

Here is what I am seeing, and trying to figure out what might be causing this. I an new to Blender so it is probably something basic!

thanks

Since you bought it you might have get any Email… or something about versions…
But/Or he seems to work on it ( 2 weeks ago) :

Or maybe @Cartesian_Caramel will see this here and may reply…

Ok, would be great to chat with the developer here. EMail just confirms purchase. But I see file name says V4.

thanks

Set the object normals smooth (right-click, shade smooth)
