Author Box image doesn’t show

Hello,

I help with the development on a website that has it’s focus on blog posts. There are a lot of users that are authors and we use the plugin to show them at the end of each post.

The problems is the HTML tag that contains the image of the author sometimes show and sometimes not. We checked the users to have set the Photograph URL on the Author Box for Divi settings. Can you please help figure this out?

Thank you in advance!
