Lightbox link not playing 3rd party Vimeo videos

When we created this website we attributed Lightbox links instead of buttons that played 3rd party videos from Vimeo in the “Lightbox Settings>Media>url”. We did this in order to have the video play directly on our site instead of branching out and playing it on Vimeo. I am open to suggestions on how to fix this, but would like to keep the Lightbox feature in order to play the Vimeo video on the website.

Thanks,
