View clone but different design


I have a view (block) and I see it like a ul html list but the format is “Unformatted”.
I clone this view and I dont change anything. I edit the page and change the first view for this and I see the text without desing… every line under the another without spaces, colors…

If is a clone, why the design change? and where i can modify this design?

Thanks a lot!
