on the email template, you need to get the order ID first, like:
<?php
$order_id = $order->id;
//then
$section = get_field( 'location_section', $order_id );
$column = get_field( 'location_column', $order_id );
$row = get_field( 'location_row', $order_id );
?>
<p>Location of item is: <strong>S<?php echo $section; ?>-C<?php echo $column; ?>-R<?php echo $row; ?></strong></p>
