Different settings can be disabled/modified in the layers palette A rainbow appears on some of the presets and has a blur applied. If the rainbow looks too blurred or not blurred enough, you can easily modify it. In the history, go back one spot to undo the blur (the blur is the last to be applied). Then redo the blur with the setting that best suits your photo. You can also change the intensity of the rainbow or how it is applied by modifying the top layer.
