woothemes flexslider controlNav property is not hiding when set to false

Question

enter image description here the problem is that the bullets at the bottom of the image aren't hidden even when their showing property is set to false

// Can also be used with $(document).ready()
jQuery(window).load(function() {
    jQuery('.flexslider').flexslider({
      animation: "slide",
      touch: true,
      directionNav: false,
      smoothHeight: true,
      controlNav: false,
      directionNav: false,
    });
  });

i was expecting the bullets to hide
