Lightbox - not showing Image

I am building our Portfolio in Webflow. Now, for our Animation, I could link the lightbox without a problem. It is working.
So I wanted to do the exact same to our Logo Showcase, but it doesn’t matter what I do, the lightbox won’t show the Images when clicking on the box. I don’t know what I am doing wrong…

I’m having the same problem with linkboxes right now and videos. I’ve seen others posting as well. This must be a bug.
