How do I set to collection level scope instead of environment level scope?

I have a collection variable called billerCode. It seems to work sometimes, but sometimes not. And the UI right now says its looking at the environment level for the scope.

If the variable is a collection variable why is it looking for an environment variable? Is there a way to use collection variables here?

I think I found the issue, once I opened environment variables I had a variable named the same. But it wasn’t showing when I clicked the eye icon, only when I opened up all the environment variables.

Can delete this topic, just a noob issue basically.
