CMS Vimeo thumbnails not showing up in image/background image, Lightbox Issue

Hi!

I ran into an issue where my CMS Collection page is having trouble displaying Vimeo thumbnails in a Lightbox.

Here’s what i’m trying to do, CMS director’s have 1-8 vimeo links in their collection fields. When we click on a director’s name i want their director page to display those vimeo links in a grid with lightbox enabled thumbnails. The issue is, they’re not appearing as background images or as images, but in the published site i know they’re there, the lightbox function works but they display these colored bars as thumbnails within an opened lightbox
