Wrong Author Name on the Main Page

https://www.redpolls.com

On the main page, author of the every post getting same nickname(admin’s nickname), but when you click the post, for example; https://redpolls.com/luffy-vs-zoro/ , you can see the name of the real author. If you also check the Top Rated and New Posted, still everything is okay.

I’m using the same thing to get author names;

<div class="div_auth_home">By: <span><a href="https://redpolls.com/?page_id=775&user=<?php the_author_meta( 'id' ); ?>"><?php echo get_the_author( 'ID' ); ?></a></span></div>

I really don’t get it why on the main page its not working and everywhere else it’s working.

I’d be grateful if you can help me.
