Creating multiple sliders?

I’m liking that I can use CPT’s in the Smooth Slider, but for the life of me, I can’t figure out how to create a second slider. I have looked on the web for solutions, but the ones I find list things that my copy doesn’t have or do. For instance, I’ve read when you check the multiple box, it will offer you buttons for creating additional sliders. Nope. Never.

I need differing widths (to put some on pages, some in widgets) but without the ability to create more sliders – how can I do this?

Am I missing something?
