Image Slider module will not add more images

The image slider module is not allowing the "Add Images" or "Manage Slides" buttons to be clicked. The module seemed to work fine in the past, but isn't working correctly now. Any ideas?

Have you tried another browser or clearing the cache?

Thanks for the reply! Yes, I've tried both to no avail. I did notice the issue only happens in Design Manager on the template, and not in a published page.
