Shortcode is showing text not url

Hi!

I′m having problems to show an url from a ACF shortcode. As you can see on ¨Ficha Técnica¨ link is not working.

/////////////////////////////////////////

This is the code in file funtions.php

// Remove the additional information tab
function woo_remove_product_tabs( $tabs ) {
    unset( $tabs['additional_information'] );
    return $tabs;
}

add_filter( 'woocommerce_product_tabs', 'woo_remove_product_tabs', 98 );

/**
 * Add a custom product data tab
 */
add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab' );
function woo_new_product_tab( $tabs ) {
	
	// Adds the new tab
	
	$tabs['test_tab'] = array(
		'title' 	=> __( 'Ficha técnica', 'woocommerce' ),
		'priority' 	=> 20,
		'callback' 	=> 'woo_new_product_tab_content'
	);

	return $tabs;

}

/**
* Content Manual TAB
*/

function woo_new_product_tab_content() {

// The new tab content

echo do_shortcode( ‘[acf field=”pdf_media_file”]’ );

}
