Second instance of slideshow not loading on iOS devices

When placing two galleries on the same page using the NextGEN Pro Thumbnail gallery, the second gallery does not display the images when clicked. The grid shows up fine on the page, however, when the image is clicked the loading image shows briefly, then a blank black screen.

This appears to be an iOS Safari issue only.
