Logo on archive page doesnt appear sometimes

this is weird, really weird
Using a custom template for archive, i used the following code do display the brand logo on archive page.
Sometimes it works, but for some brands, it shows nothing.

Any clue ?

//Brand hero page shortcode
function custom_pwb_brand_info() {
    if( is_product_taxonomy() ){
    $brands = wp_get_post_terms( get_the_ID(), 'pwb-brand' );
    
    foreach( $brands as $brand ) {
      $attachment_id = get_term_meta( $brand->term_id, 'pwb_brand_image', true );
      $attachment_src = wp_get_attachment_image_src( $attachment_id,'full' );
      $brand_banner_id = get_term_meta($brand->term_id, 'pwb_brand_banner', true);
      $brand_banner_src = wp_get_attachment_image_src( $brand_banner_id,'full' );
      echo '<div class="row align-items-center">';
      echo '<div class="col-12 col-sm-6 text-center">';
      echo '<img src="'.$attachment_src[0].'" alt="">';
      echo '<p>'.$brand->description.'</p>';
      echo '</div>';
      echo '<div class="col-12 col-sm-6">';
      echo '<img src="'.$brand_banner_src[0].'" alt="">';
      echo '</div>';
      echo '</div>';
    }
  }
}
add_shortcode( 'custom_pwb_brand_info', 'custom_pwb_brand_info' );
