Updated password saved through browser extensions does not update browser history?

Hi @Pumbania thanks for getting back to me!

While I can't provide a specific timeline for a fix for this issue, our developers have been working to get this resolved as soon as possible, and you can keep an eye on our release notes page for news: 1Password Releases

Is it possible that you created this item in another vault and then moved it to the current vault it is in? The item history is not kept in that case. If you can find the original item in the original vault recently deleted section on 1Password.com you can restore it. Let me know how it goes!
