Diesen code snippet in die functions.php

add_action( 'restrict_manage_posts', 'shop_order_user_role_filter' );

	global $typenow, $wp_query;
	if ( in_array( $typenow, wc_get_order_types( 'order-meta-boxes' ) ) ) :
		$user_role	= '';
		// Get all user roles
		$user_roles = array();
		foreach ( get_editable_roles() as $key => $values ) :
			$user_roles[ $key ] = $values['name'];
		endforeach;
		// Set a selected user role
		if ( ! empty( $_GET['_user_role'] ) ) {
			$user_role	= sanitize_text_field( $_GET['_user_role'] );
		}
