Azure, click over to the full-size image on its own page--that's where you will find the source citation below the image. It is not empty. I have been using this citation on my profiles for the past couple of weeks since the other citation on the index page is empty. Here is one of my profiles using the 1940 U.S. Census citation in which the link takes you directly to the image. You can add a link to the index page or replace the image link with the index link if you wish.
Edited to change link.
