Does not work Auto-compile after entering the "Value"

Sorry, I was hasty. It's Constant Vectors → Value.
In order:
1. I opened the "ShaderForge\Example Assets\Shaders\Tiles.shader"
2. Change the "Value" of "Exp" in "Power" or "A" in "Multiply".
3. Change the focus (for example to another node) - auto-compile does not work.
