Replace line 314 in file wp-admin/includes/class-wp-users-list-table.php with:

<?php
<?php 
            if ( $this->is_site_users ) {
                switch_to_blog( $this->site_id );
                wp_dropdown_roles(); 
                restore_current_blog();
            } else {
                wp_dropdown_roles();                
            }
            ?>
