I have confirmed that all images are in the same slider category. No matter which slider I use only one image will show. I have checked the slider settings to make sure more than 1 is allowed to show.
I am having this same problem. My slide show number is set to 0, 3, 10 any number...it still doesn't work. It only seems to display the feature image as whenever I change the feature image, that is what is displayed.
