Carousel Gallery Showing Only One Image At A Time

I'm trying to use a slideshow gallery but for whatever reason it isn't working properly, it won't show all the slides (usually only the first slide) and glitches out and just goes blank for long periods of time. The gallery works properly when I change the style to any of the other gallery options so I'm trying to find a way to use the carousel gallery but can't seem to find the right bit of code to get it to only show one slide at a time. 

Any help would be appreciated!
