Thumbnails Will Not Lazy Load

I can see that images on a single post load fine. But they do not lazy load any of the thumbnails I have on my blog page, home page, or any pages with thumbnails.

On the single post images, I see the data-lazy-loaded=”true” attribute in the img output, and can also see the fade in affect on the images. But on the thumbnail images, the data-lazy-loaded=”true” attribute is not there, and there is no lazy load.

I am using version 0.5 of the plugin, on the Genesis framework (v 1.8.2).

Any help is greatly appreciated!
