Thank you for reaching out to the Community!
I am sorry to hear that you are having troubles resetting that password. From what you mention it sounds like you may be logged in as an additional account user. That said, there is another way to reset your password. Click Here for a support article that goes over this process. If you are still experiencing issues changing your password after following these steps then I would suggest calling our support team as we are only able to offer limited account access support over the Community.

I hope that this helps! Thanks and have a great rest of your day!
