FF Plugin doesn't remember last used login anymore when auto-filling

I’m having a problem with auto-filling for some time now. There are a lot of websites where I have multiple login credentials. When I used CTRL+SHIFT+L in the past to auto-fill the login, it just used the credentials I’ve used the last time but this doesn’t seem to work anymore, even in the same session. For example, when I try to log in to Amazon, the first suggestion from Bitwarden is my dads credentials, so I press CTRL+SHIFT+L again and now I get my own credentials and log in. Then I log out again and try to log in again an the first suggestion is my dads credentials again.

Any idea why this doesn’t work anymore?
