Slider will not function

I have created a slide and have put some content in. A review from an ex tango student. However when I copy of the slide it does not slide. I created another slide and placed the comment of another student. Now the slide functions but it moves both slides together instead of separately. I have tried various remedies but to no avail.

Go to slider settings and you can play with the different options there:
