    Because it is relationship custom fields it needs another loop inside

    $post_id = get_the_ID();
                    //echo $post_id;
                    // $entos_edras_omada = get_field('entos_edras_omada',$post_id); 
                    //$dish_meta = get_post_meta( $post_id, '_entos_edras_omada', true );
                    //echo $dish_meta;
                    //echo $entos_edras_omada;
                    ?>
                    <?php
                        $featured_posts = get_field('locations');
                        if( $featured_posts ): ?>
                            <?php foreach( $featured_posts as $post ): 

                                // Setup this post for WP functions (variable must be named $post).
                                setup_postdata($post); ?>
                                
                                    <span><?php the_field( 'entos_edras_omada' ); ?></span>
                                    
                            <?php endforeach; ?>
                            <?php 
                            // Reset the global post object so that the rest of the page works correctly.
                            wp_reset_postdata(); ?>
                        <?php endif; ?>

    You shouldn’t need to setup_postdata when you’re within the loop. I’m not sure that I understand $headlines_lead = get_field('sixed_relationship','alpha_brief', false); This looks incorrect to me. What kind of field is this? I’m guessing a relationship field and you’re trying to get an array output of post IDs, correct?

    Try this:

    <?php
$headlines = 0;

$headlines_lead =  get_field('sixed_relationship', false, false);

$args = array(
    'posts_per_page'    => 4,
    'offset'            => 0,
    'post_type'         => array('analysis_stoiximatos', 'printed_post'),
    'post__in'          => $headlines_lead,
    'post_status'       => 'publish',
    'orderby'           => 'post__in'
);

$banner_query2 = new WP_Query( $args );
?>

<div class="central_main_area">
    <h1>matches </h1>

    <?php
    if( $banner_query2->have_posts() ):
        ?>
        <ul>
            <?php
            while ( $banner_query2->have_posts() ) : $banner_query2->the_post();
                ?>
                <li>
                    <a href="<?php the_permalink(); ?>">
                        <?php
                        the_title();
                        var_dump(the_field( 'entos_edras_omada', get_the_id() ));
                        ?>
                    </a>
                </li>
            <?php endwhile; ?>
        </ul>
        <?php
    endif;
    wp_reset_postdata();
    ?>
</div>
