Views Slideshow and Colorbox

Hello everyone!

I'm not sure if I'm riting in the write place but I need help! I'm using drupal 7. I've created a Slideshow using Views. The View contain's an image field that have the format colorbox. The problem is that every image in the slideshow and inside the colorbox is duplicated.

http://nuoveenergie.lab.develon.com/it/macchinari/ultrascreen is here where you can see the problem. There are 3 images inside the field but it's showing up 6. I hope I made myself clear.

Thanks in advance!
