Author name and link not displaying at posts of the front page loop

Hello! I just started my website www.wumanity.com and I am using Gridalicious, and it is just so great! Thank you! On the loop home page, with the latest posts at the timeline, there is a problem. It only displays the date and the edit link, but not the author name. Is that possible to fix it? I do have a child theme, also with that content-page.php it was recommended in this question https://catchthemes.com/support-forum/topic/author-and-updated-missing-in-pages-structured-data/ but it is still not working to the author show up. Plus, I would like to have this 3 information at the footer of the post. Thank you in advance. Best regards, Rossana
