There is a bug with the beaver builder themer plugin which started to happen a few versions ago.
With the latest versions, the featured image is not the correct image being shown. In our site we have a featured post at the top of the page with its own layout, and then the older posts below it. I believe this happens when there is a multiple posts being shown on the same page.
I wasn’t able to find the actual bug causing this, but I was able to narrow it down and find a workaround in the meantime. I also wasn’t able to hook the function. Hopefully this workaround will help show you what is going on code wise so you push out a fix, or make it hookable so I can make it properly on my end so I can keep it updated.

FUNCTION: get_featured_image_url()
REPLACE ENTIRE FUNCTION WITH:
static public function get_featured_image_url( $settings ) { global $post; $fi = get_transient( 'featured_blog_image_url_temp' ); $featured_image = unserialize($fi); if(is_singular('post')){ //single image if($featured_image['id']!=$post->ID){ $id = ''; $url = ''; if ( has_post_thumbnail( $post ) ) { $id = get_post_thumbnail_id( $post->ID ); $url = get_the_post_thumbnail_url( $post, $settings->size ); } elseif ( isset( $settings->default_img_src ) ) { $id = $settings->default_img; $url = $settings->default_img_src; } return array( 'id' => $id, 'url' => $url, ); } } else{ //featured image if($fi && $fi!=''){ $id = $featured_image['id']; $url = $featured_image['url']; } else{ $id = ''; $url = ''; if ( has_post_thumbnail( $post ) ) { $id = get_post_thumbnail_id( $post->ID ); $url = get_the_post_thumbnail_url( $post, $settings->size ); } elseif ( isset( $settings->default_img_src ) ) { $id = $settings->default_img; $url = $settings->default_img_src; } set_transient( 'featured_blog_image_url_temp', serialize(array('id'=>$id, 'url'=>$url)), 86400 ); } return array( 'id' => $id, 'url' => $url, ); } }
