Morph Accordion Help?

Hi All, 

Hoping someone can help. I am trying to create an accordion style menu for a learning module using the morph transition.

I have tried multiple times but I cannot get it to work. Once I create my base slide, I have duplicated it, moved the assets to the places where I want them to be, but once I preview, the assets don't slide smoothly across the screen, they fade out at the same time as sliding, and then reappear in the final location. Its driving me crazy! I do not have any animations on any of the slides, I have not added anything new to any of the slides, they are all exact duplicates of the original, only the location of assets on the page has changed. I have attached the .story file, hoping someone can tell me where I am going wrong. 

Thanks 

John
