Content is the same everywhere

Hello !

Thank you for your work on this plugin, it seems to be just what I was looking for.

But I have a problem : I added 4 different posts (with different dates, titles and contents of course), I added the shortcode on a page, my timeline looks nice (with the different dates) but everytime I click on another year, the first post stays and I can only see this one (the first I created).

Am I missing something? Thank you in advance for your answer.

David
