Could you provide more context or specify what steps or process you're referring to? From your attached screenshot it looks like the data was added trice.
Dear Shen_Zang and mauriziobombace
I have a similar problem: the List widget is flakey - sometimes it works and sometimes it doesn't.
A common problem is that when I set a View, and apply it to a List, the first item is repeated for the entire list.
Sometimes when it does this, if I re-apply the View to the list it works (but absolutely nothing changed in my actions from the first to the second time I applied the View).
Other times I can't fix it: see attached screenshot.
Thanks in advance

Having the same issue in a List. If I use Auto-populate the sorting does not always work correctly. The list sometimes starts at item 4, sometimes 7, sometimes 6, sometimes 1. From whatever number it starts from the sequence is correct after that (ie, 4, 5, 6 or 7, 8, 9) but the "lost" numbers from the front (eg, 1, 2, 3) are at the bottom of the list.
I have tried sorting and filtering the list itself and the dataset. Doesn't help.
