pdb-list template export not working correctly since last update

I have created the following template over 1.5 years ago, and I am calling it from a page with the following shortcode:

[pdb_list template=mcard orderby=”first_name” order=”asc” filter=”mtype=Member&paid_year=2022″ fields=”first_name, last_name, paid_year, maac, status”]

The content of the pdb-list-mcard.php located in the /public_html/wp/wp-content/themes/colormag-child/templates folder is:

<?php
/*
 *
 * template for participants list shortcode output including a CSV download form
 *
*/
?>
<div class="wrap <?php echo $this->wrap_class ?>" id="<?php echo $this->list_anchor ?>">
<?php
  /*
   * SEARCH/SORT FORM
   *
   * the search/sort form is only presented when enabled in the shortcode.
   *
   */
  $this->show_search_sort_form();

  /* LIST DISPLAY */
  /* 
   * NOTE: the container for the list itself (excluding search and pagination 
   * controls) must have a class of "list-container" for AJAX search/sort to 
   * function
   */
?>
  <table class="wp-list-table widefat fixed pages list-container" >

    <?php 
    // print the count if enabled in the shortcode
		$this->print_list_count($wrap_tag = false); 
    ?>
    <?php if ( $record_count > 0 ) : // print only if there are records to show ?>

      <thead>
        <tr>
          <?php /*
           * this function prints headers for all the fields
           * replacement codes:
           * %2$s is the form element type identifier
           * %1$s is the title of the field
           */
          $this->print_header_row( '<th class="%2$s" scope="col">%1$s</th>' );
          ?>
        </tr>
      </thead>

      <tbody>
      <?php while ( $this->have_records() ) : $this->the_record(); // each record is one row ?>
        <tr>
          <?php while( $this->have_fields() ) : $this->the_field(); // each field is one cell ?>

            <td class="<?php echo $this->field->name ?>-field">
              <?php $this->field->print_value() ?>
            </td>

        <?php endwhile; // each field ?>
        </tr>
      <?php endwhile; // each record ?>
      </tbody>

    <?php else : // if there are no records ?>

      <tbody>
        <tr>
          <td><?php if ($this->is_search_result)  echo Participants_Db::$plugin_options['no_records_message'] ?></td>
        </tr>
      </tbody>

    <?php endif; // $record_count > 0 ?>

	</table>
  <?php $this->show_pagination_control(); ?>
  <?php
  /**
   * prints the CSV download form
   *
   * @see full instructions on https://xnau.com/adding-a-csv-download-button/

   */
  $config = array(
		'title' => '',
		'helptext' => 'Click the "Download" button above to get the current membership list form membership cards',
		'button_text' => 'Download',
		'filename' => 'XXXXX-membership-card-list',
		'allow_user_filename' => 'True',
		'export_fields' => array( 'first_name', 'last_name', 'paid_year', 'maac', 'status', 'id' )

		); // this shows the form with all default values
  $this->csv_export_form( $config );
  ?>
</div>

Until recently I got the export as expected, but for the past few weeks – assuming since one of the latest updates – it is exporting the list with different fields:

first_name, last_name, city, state, zip, maac, year_born, type, status, year_joined,
paid_year, executive_position, comments, id

it is a bit of inconvenience since our members starting to renew now, and we will need this export functionality to work almost on daily basis now.

Please let me know how can I fix this.
