Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Open the …/wp-content/plugins/mailchimp-for-wp/includes/integrations/class-integration.php file.
• Look for line 168.
• Replace:

      public function get_label_text()
      {
          $integration = $this;
          $label       = $this->options['label'];
  
          if (empty($label)) {
              $default_options = $this->get_default_options();
              $label           = $default_options['label'];
          }
          

• With:

      public function get_label_text()
      {
          $integration = $this;
          $label       = $this->options['label'];
  
          if (empty($label)) {
              $default_options = $this->get_default_options();
              $label           = __( $default_options['label'], 'mailchimp-for-wp' );
          } else {
              do_action( 'wpml_register_single_string', 'mailchimp-for-wp', 'Checkout Label', $label );
              $label = apply_filters( 'wpml_translate_single_string', $label , 'mailchimp-for-wp', 'Checkout Label' );
          }
