Problem with export in Motion app

Hello!
I'm having trouble exporting a video in the motion app. I don't know why but when I export the video it is not similar in how it is in the project view within Motion.As you can see in the images, what I do within the project has no effect on the video and it only repeats the first page instead of showing the ones I selected.
And if I save the file and enter it again, it is again all the pages are arranged only on page 1.

Please wait for an answer. thank you very much!

It is difficult to see only the captures of the clues to understand what is happening in your video. I think the best advice may be to see Mark Spencer's Motion tutorial (it's very good)
