Override templates not working

Hi,

I want to remove the “from” part from the shortcode room-rates price. What I did was copy the rate-content.php file from /wp-content/plugins/motopress-hotel-booking-lite/templates/shortcodes/room-rates/ to /wp-content/themes/my-child-theme/hotel-booking/shortcodes/room-rates/ and changing the output string like below but it doesn’t work:

<?php
/**
 * Available variables
 * - string $title
 * - string $minPrice
 * - string $description
 */
if ( !defined( 'ABSPATH' ) ) {
	exit;
}
?>
<?php do_action('mphb_sc_room_rates_item_top'); ?>

<?php // phpcs:ignore WordPress.Security.EscapeOutput.OutputNotEscaped
echo $title; ?>, <?php echo wp_kses_post( sprintf( __( '%s', 'motopress-hotel-booking' ), $minPrice ) ); ?>
<br/>
<?php // phpcs:ignore WordPress.Security.EscapeOutput.OutputNotEscaped
echo $description; ?>

<?php do_action('mphb_sc_room_rates_item_bottom'); ?>

Does overriding of templates only work with the premium version of the plugin?

Thanks
