Q:

FlexSlider Auto Height still leaving a space below slider

I have auto height on my flexslider and its still leaving a space below it.
I have applied a background colour to the slider and it is using auto height and moving up and down but it seems like the slider is taking the biggest photo and keeping the slider at that height.
Any help would be great!

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>

This is my css:

And this is my javascript:
<link rel="stylesheet" href="css/flexslider.css" type="text/css" media="screen" />

            <script type="text/javascript">
            $(window).load(function() {
              $('#carousel').flexslider({
                animation: "slide",
            animationLoop: true,
            itemWidth: 200,
            itemMargin: 10,
            minItems: 5,
            move: 5,
            controlNav: false,
                asNavFor: '#slider'
              });

              $('#slider').flexslider({
                animation: "fade",
                controlNav: false,
                animationLoop: true,
                slideshow: false,
                smoothHeight: true,
            slideshowSpeed: 20000,
            directionNav: false,
                sync: "#carousel"
              });
            });
        </script>

A:

#slider
