Problems logging into my AWS training and certification account

I wrote the cloud practitioner exam and I registered with an email. However, now I'm trying to log in using the same email into the AWS training and certification portal but I keep getting this message. ( an account already exists with this email address. if you are an APN partner or amazon employee, please using the appropriate option to access your account). How can one resolve this error because I don't want to create a new account so I can have all the exam histories and my certifications on one account.
