Lightbox under fixed navbar and images cut off

Hi there! I’m having an issue with a CMS-driven Lightbox page. When I click on the image, it shows only half the image in the big view.

The other issue I’m running into is that the Nav bar is still above the Lightbox, even after making the Lightbox have a higher z-index than the nav bar. I’m not sure what I’m doing wrong.

The Lightbox is at the bottom of the page. Let me know if you need anything else to help.
