Widget Logic Plug-in

I installed this plugin with hopes of being able to control sidebar widgets for different pages. Trouble is ( for example ) when entering the correct conditional tag for individual page ( logic ) removes the widget from everywhere . If I paste is_page( ‘business-cost-reductions’ ) in the space provided it removes the widget from all pages, not just the page entered into the widget logic control.

I guess I’m wondering if this widget is easy out the box, or requires lots of tweaking? Any feedback is appreciated..
