Hello @guycantin
Thank you for contacting the Community.
Upon checking your account, we noticed you are using the web (lastpass.com) rather than the extension.
The most common reason for this happening is that LastPass data was inadvertently saved to your browser's bult-in password manager. If you have stored your Master Password in your browser, please delete it, then you should no longer have this issue.
Thank you,
