I have mistakently filled out the data challenge is there anything I can do now?

Pretty much the question in title. I had stupidly forgot about the warning that had been given in one of the lectures. And I filled all the fields with jargon to check that the “get your certiificate” button would pop up. Now I cannot retake the challenge and submit actual answers.
Is there anything that can be done now?
I understand that this is my mistake.
