Toggle key doesn't work? (using latest 2.0)

So i'm using the reshade assistant, the latest version 2.0 found on the main page.

I've created a new game profile > choose the .exe > choose default preset > Choose shaders > Profile settings > toggle key is "VK_SCROLL" > save + confirm

Now i'm assuming you can't change the "range : undef" because i havn't found a way to.

With those following steps, the toggle key does nothing. Did i miss something or does the toggle straight up not work?

I've googled and searched and can't find anything relevant
