Shader Graph Issues

I've had this issue with shader graph since last year and I'm not sure why it's happening. So when I go into Unity and open shader graph, I try to make a simple shader like alpha blend and it doesn't seem to work properly.
on the left is what i made today, and on the right is something I made previously last year before this issue erupted. As you can see both have about similar settings with regards without a split on the left, and yet it doesn't want to function properly. I just want to know whether it's I'm doing something wrong, or is it just shader graph just not functioning properly. Same goes when I try to make pbr graphs as well.
