Slideshow Buffers Forever?

I downloaded this plugin and am experiencing massive buffering issues.

I currently use a plugin called “page builder by SightOrigin” in order to create webpages. I have created about 5 slideshows and none of them have worked. They all load with a buffering wheel and continue to buffer indefinitely.

I have changed the sizes of the images I uploaded, but that did not help.

I think there might be a conflict between these two plugins, but I have no idea how to reconcile this issue.

Any help would be appreciated.
