Could you show your plugin parameter with all the conditions? All I see from the image is there is no switch condition.
It is odd as I cannot reproduce the issue in my test project. Are you sure you don't have a dispel herb in your inventory? Do you have any errors or warnings in the dev tool console if you press F8? Do you have any non-CGMZ plugins, and could you try temporarily turning them off to rule out a conflict if so?
