Duplicated profile images in commenters??

For instance, the following page: https://bitsum.com/parkcontrol/

You will see a list of commenters, but all appearing to have our *internal* image icon. Where did their profile icons go? I figure the server-side rendering makes this a probable buck of the WordPress plug-in? Please let me know what you think.

Note I did recently import the comments into WordPress, whether related or not.

Thanks!
