Since your account was created using your Facebook credentials these changes could take up to two weeks to be updated on Spotify's side.
If the changes aren't reflected in your Spotify account after this period of time, pleasetry clearing your browser's cache and logging out and back into your account. If the problem persists, I would recommend contacting the Spotify customer support team using the online contact form. They should be able to help resolve this issue.
Let me know if you have any questions. Happy listening 🙂
