Cookie Pop up changing after adding a Shortcode

Hi there! Thanks for this amazing plugin.

Everything was working correctly until I added a shortcode to a page and the cookie bar changed to the default message and style on that specific page. If I disable the snippet, the customised cookie bar shows up as it should.

Here is the snippet code:

function show_sites_list() {
 	if ( ! is_multisite() ) {
	wp_die( __( 'Multisite support is not enabled.' ) );
}
    $user_id = get_current_user_id();
    if ($user_id == 0) {
		$html = 'Debes iniciar sesión para ver tus sitios.';
    } else {
        $user_blogs = get_blogs_of_user( $user_id );
		$html = '';
		$html .='<div id="myblogs" method="post">';
		foreach ($user_blogs AS $user_blog) {
			switch_to_blog( $user_blog->userblog_id );
			$html .= '<div class="card">';
			$html .= '<h3 class="card-title">'. $user_blog->blogname .'</h3>';

		$actions = "<a href='" . esc_url( home_url() ) . "' target='_blank'>" . __( 'Visitar' ) . "</a>";

		if ( current_user_can( 'read' ) ) {
			$actions .= "<a href='" . esc_url( admin_url() ) . "' target='_blank'>" . __( 'Escritorio' ) . "</a>";
		}

		/**
		 * Filters the row links displayed for each site on the My Sites screen.
		 *
		 * @since MU (3.0.0)
		 *
		 * @param string $actions   The HTML site link markup.
		 * @param object $user_blog An object containing the site data.*/
		
		$actions = apply_filters( 'myblogs_blog_actions', $actions, $user_blog );
		$html .= '<p class="my-sites-actions">' . $actions . '</p>';

		/** This filter is documented in wp-admin/my-sites.php*/
		echo apply_filters( 'myblogs_options', '', $user_blog );
		$html .= '</div>';
	}
	$html .= '</div>';
 }
	return $html;
}
add_shortcode( 'siteslist', 'show_sites_list' );

I tried everything but does not work. I hope you can help me.

Thanks!!
