Product Landing Page - Build a Product Landing Page

I submitted this project months ago, when the fcc offered making projects in codepen and submit the link as solution. But I’ve now deleted the codepen and I can’t download my solution, nor am I able to submit a new solution, even though I’ve solved in fcc’s built-in code editor for projects too. It doesn’t pass some test-suites but I thought it’d at least work as my latest solution, and replace the link to codepen.
Please guide me, what’s happening.
