Hhm. I'm not sure what might have happened, but there are no clones in the file. But it's not all bad news.
First, when you select one of the images, look at the status bar (middle-bottom of window) and it will tell you what kind of object it is. Except for the one in the top-left corner, they are all Groups. It's possible you were clicking the Group button instead of the Clone button.
So you could either use one of those Groups, and create new clones from it, or you could use the one in the top-left corner. The only difference is that the one on the corner is not a group. It doesn't really matter which one you use. But if you use the one in the corner, just make sure you have selected all the pieces, before you clone it. This is the Clone button:
Also, I noticed that you have used Flowed Text, which can be a problem in some situations. I guess you will be printing these, and I can't think of any problems with Flowed Text and printing. But my memory isn't so good. So if you have a problem with the text, you can probably solve it by converting the Flowed Text to regular text. Text menu > Convert to Text. You might have to re-align the text after you do that. But at least you'd only have to do it once.
