Item names disappeared on the timeline and no longer show up in publish or preview

Hi Jurgen.

Thanks for your quick reply.

I guess I could do that. I don't have this in layers, though I suppose I could make this interactive and use it like a quiz. I'm just not sure they will remember enough at this point which is why I did the whole thing on one layer. I wanted them to see the pattern of the back and forth between the two screens.

There wasn't an import. I downloaded each of the numbers by Insert>Icons and searching for the number. Then I made them pink, and smaller, and renamed them by their number instead of Icon #whichever I downloaded their order in. It gets so confusing if you don't name them. I downloaded the icons for browser, and command prompt, then I typed the text for each. 

But I did that for all the numbers which is why I'm so puzzled. I suppose I can redownload those four numbers and try again but I'm hoping to avoid whatever went wrong so I need to know what might have caused this.
