Media Lib check box wont remove image from slider

I’m having the same problem. Have also noticed that the Smooth Slider options is showing up twice in the media library posts – once directly below the description and again as a screen option.

You can go directly to the slider plugin page to remove a specific slide and this change will apply to the media library, but it is not as convenient as using the media library to browse photos and select or un-select them for the sliders.
