It's really bad at automatically detecting account creation and password change forms (a lot worse than OnePass and Firefox password manager) so if you're not careful to tell Bitwarden you're password manually it can cause problems.
Still my password manager of choice since it's free, open source, and feature-full.
Thanks for the support and feedback, it can help to disable your browser's ability to manage credentials: https://bitwarden.com/help/getting-started-browserext/#disable-a-built-in-password-manager or contact the support team directly at https://bitwarden.com/contact/
