[Plugin: NextGen Gallery] – Lightbox Images showing twice

Hi,

Im using nextgen gallery to showcase images, I know when I first set it up it was working fine but i noticed today that when I click a thumbnail to view the image in the lightbox the same image is shown as I scroll through.

Say I click thumbnail no.1 it shows me image no.1 but then when I click next in the lightbox to view image no.2 it shows no.1 again.

Here is the page: http://breakbulkschedules.com/break-bulk-gallery/

Help would be great.

Many thanks
Nick
