Slider auto height not working?

Hi there,

It would seem that the auto-height button isn’t working. I would like my slideshows to be 100% responsive, and adhere to both the width and height of any screen/media. If anybody can suggest any solutions then I’d appreciate it very much. Simply setting the width and height within the plugin settings for each slideshow isn’t enough for me as I have numerous images of differing aspect ratios and cropping isnt an option.

See my (beta) site for reference:
