Can't change PBR Master settings

So copied the brackeys cartoon water as the base of my water shader but I am unable to change the mode from opaque to transparent for some reason. I have assigned it in the graphics settings and everything but when i go to click on the settings, nothing happens! No popup menu, no error, nothing. Someone now what to do here?

 

Is it shadergraph shader or usual one?

 

This sounds like something that happened to me, I upgraded URP then it was okay (newer version of Shader Graph, if the little settings icon in the older version is what you're talking about).
