Facebook password change not updating

Has anyone else seen any issues in changing passwords on Facebook? Both my wife and I changed our passwords (using Chrome), and when the auto-update prompt came up it created a new entry with a user of ‘3’ and the old password, effectively forgetting the new one. Luckily the generator history saved our butts here, but it is a flaw that prevents me from recommending Bitwarden to people like my parents/grandparents.

Is there anything we did wrong using the update option, or is this some sort of security feature with Facebook to keep bad actors at bay?
