I'm afraid it doesn't look like your project has been saved. In order to save your project you need to make sure each of the boxes is full and you have no error messages at the top of the page.
You can fill in with any text and then come back to it to work on it another time. Just click 'Submit' when you're happy with it.
I have lost my work like that too. There is no warning that your project gets deleted when you click Save for Later unless you have filled in all boxes. I urge the team to correct that promptly, or remove the Save for Later option.
