FlexSlider Auto Height по-прежнему оставляет пространство под слайдером

У меня есть автоматическая высота на моем flexslider, и он все еще оставляет пространство под ним.

Я применил цвет фона к ползунку, и он использует автоматическую высоту и перемещается вверх и вниз, но похоже, что слайдер делает самую большую фотографию и удерживает ползунок на этой высоте.

Любая помощь была бы замечательной!

This is my html:
<div id="carousel" class="flexslider">
<ul class="slides">
<li class="slide">
<img src="<?php echo $thumb_image; ?>" />
</li>
</ul>
</div>

<div id="slider" class="flexslider">
  <ul class="slides">
    <li class="slide">
       <img class="slidermainimg" src="<?php echo $main_image; ?>" />
    </li>
  </ul>
</div>
