Password app redundant confirmation prompts for login credentials (password is already saved)

I use the Passwords app as my main password manager. Since iOS26/ iPadOS26, even with long-saved passwords and passwords I’ve just newly created or updated, the next time I login it prompts me whether I want to save it and it only has the password saved, but not the username or email I know for a fact it already has saved.

Why is it doing this? I haven’t changed any of my user behaviours, just updated my OS across all my devices (which are all recent enough to be receiving OS updates).
