Oh, thanks for the tip! It works if I comment out this filter:

//change pdf-name
add_filter( ‘wpo_wcpdf_filename’, ‘wpo_wcpdf_custom_filename’, 10, 4 );
function wpo_wcpdf_custom_filename( $filename, $template_type, $order_ids, $context ) {
if(get_locale()==”et”){

$invoice_string = _n( ‘invoice’, ‘invoices’, count($order_ids), ‘woocommerce-pdf-invoices-packing-slips’ );
$new_prefix = _n( ‘Arve’, ‘Arved’, count($order_ids), ‘woocommerce-pdf-invoices-packing-slips’ );
$new_filename = str_replace($invoice_string, $new_prefix, $filename);

return $new_filename;
}

}

It’s get_the_category_list and it’s inside the loop

<?php
                /* translators: used between list items, there is a space after the comma */
                $categories_list = get_the_category_list( __( ' ', 'requiredfoundation' ) );
                if ( $categories_list ):

            ?>

                <?php printf( __( ' %2$s', 'requiredfoundation' ), 'entry-utility-prep entry-utility-prep-cat-links', $categories_list );
                 ?>

            <?php endif; // End if categories ?>
