NEED HELP Sumbiting Exercise Tracker. I've finished it

Tell us what’s happening:
I finished the Exercise tracker project, and when I submitted they said it is OK, but it does not save the progress, so when I try to claim my certificate of API and microservices it appears like I have not done the project jet… After submitted, again and again, everything still the same. IDK what can I do in order to get my certificate PLEASE if someone has gone through this, or knows the solution, please let me know.

Your code so far
