Advanced Carousel does not hide items in the previous row

Hi there,

Great plug-in! I like it a lot. As you can see on my website, the items in the next row appear on the right side of the carousel, although I set the value “No” on the “Show hidden item” option. Could you tell me how to edit this to really hide the items? I would like to show only items in the current row. Thank you in advance for your support!
