WP jQuery Lightbox displaying alt text in stead of title

I’ve just changed to WP jQuery Lightbox from another product. It seems that WP jQuery Lightbox is displaying the alt text in stead of the title text of images when previewing them. SEO requires that we add alt text for our images (for non-human visitors) and we add captions to our images (for our human visitors). So I keep them the same. But because WPJLB is displaying both alt text and caption, there are duplicate description below images when viewing them in the image viewer. Here as some screenshots:

http://puu.sh/4n23k.jpg (both are showing up under the image)

I read somewhere that the plugin author feels both title and caption should be displayed under image previews, and that is fine, because if I leave the title blank my problem is solved. But now it seems to grab the alt text if the title is empty.

The page URL is http://www.elephantplains.co.za/big-5-blog/2013/09/big-5-sightings-26-august-to-01-september/

Is there a way to prevent the title and/or the alt text to appear under the image?
