Troubles to updating front-end project links

I am a student of FreeCodeCamp for almost a year. After a good start, I stopped because I was too busy professionally. A month ago, I resumed studies from scratch. Since I was not happy with my first two front-end challenges (on CodePen), I did it again. But when I try to update the project links on my dashboard, I can not do it. What should I do ? Will not that hurt me?
