Lightbox Opening to Last Image

I purchased the Grand Standard template and am having some trouble with the Lightbox feature. I thought I had messed something up, but I went back to preview the original template and it has the same issue. When you click “View Image Gallery”, it automatically shows the last image in the Lightbox and you then have to scroll backwards to see the rest of the images. How do I get it to open to the first image?
