Translation of some strings

Hello, I have a problem with WooCommerce translation. I set the language to Suomi (Finnish) in WordPress settings and many WooCommerce strings got translated. But there were inscriptions “Next”, “Previous” in the pagination and a message about an empty cart in English. In the .po file, I found a line that translates the message “No products in the cart”, but it doesn’t work. I wanted to translate the strings “Next” and “Prev” using the function, but this did not work either. How can I fix this problem?

add_filter( 'woocommerce_pagination_args' , 'fin_override_pagination_args' );
function fin_override_pagination_args( $args ) {
	$args['prev_text'] = __( 'Edellinen' );
	$args['next_text'] = __( 'Seuraava' );
	return $args;
}
