NextGen Slideshow Widget Won’t Save Changes

I’ve got the nextGen Slideshow Widget working, but I only want it to show one gallery, not all three. When I change the options in the plug-in dashboard section it shows that it has been saved. However, when I close the widget and view the page, it’s reverted back to showing all galleries. It also won’t save the height/width changes.

Any suggestions or fixes? https://www.fittothefinish.com/blog
