Content is missing even though embeds still work

When I log into H5P.org, all of the content I created last summer is gone. However, students can still interact with it in my Canvas courses. How can I access my content? I tried to access it via Chrome, Explorer, and Firefox. When I click on Contents, it says "No contents yet". I wanted to show another group of teachers who to use h5P.org on Tuesday after school with Canvas. Any help is appreciated.
