If you log in to the Spotify website online, does it display the right profile picture?
To check if facebook allws spotify, go to your fb app list.
It may take some time to update itself, so please give it a while.
Make sure when you login to press login with facebook rather than just logging in with your username and password.
Try posting here. Hopefully an admin will notice and fix it for you.
If it doesn't fix, please submit a support ticked using the online contact form, which can be found here: https://www.spotify.com/about-us/contact/
