Problem with duplicated items in products tab

I’ve a problem with “products tab element” in AJAX products tabs setting
I’ve noticed that the some items appear two times. How is it possible? Is there a way to resolve that problem?
I’ve attached an image that shows the problem.
Now I’ve hide the row for this reason.
Thanks a lot.
