I set a new set of slides in Rev Slides, and I did see the name of the new set in the drop down list, when I was trying to edit RevSlider. However after selecting it and clicking the refresh button, nothing happened. The set of the Home slides still shows up. Tried several times, and got the same result.
I use the latest Flatten, installed today, DMS 2.0.7, and the latest version of WordPress 3.9.1
