Why my course done is reset to Nothing!

I joined freecodecamp in Sept 2019 and was away for sometime, but then when I return today, I find all my courses completed reset to nothing done. Now I have to repeat all courses. Can you please look into my account and get back my courses as done before, as I don’t want to repeat the completed units.

the freeCodeCamp account is identified with the email address.

are you sure you have logged in with the same email address?
