Layouter slides not working

I followed the instructions to make slides. It resizes and the buttons work fine. But when I try to edit an item, the change appears on all five items, in the editor. So I can’t make the items different. In preview mode, ANY change I make appears only on the first item. For example, all items (duplicated) were identical. When I edit the text on item #3, the change appears only on the first item. I’m using a Macbook Pro.

in such case you can navigate with 2 options: do not display item, or dragging items. In general, renaming tool, will help you to navigate better:
