This is possibly by design, but almost hurt me. I had a password that had 3 records of saved password history. In the Password Policy tab for that site, it was set to use the "Database Defaults." I wanted to change that though, so I selected the "Use the policy below" option. When I did that, it removed my password history. I did not know this yet, so I went to the "Basic" tab and generated a new password with the newly selected policy. This almost put me in a bind as I didn't have the most recent password any longer. When I went to change my password at the web site, it asked for my prior password (which I thought was saved in the history) but it was gone. I had a backup of the passwords, but that seems odd that it would delete my history just because I change the password generation policy.
