"Password" as password shown on 1Password, and no tech support from 1Password

When attempting to log in to a target website using 1Password, my target website indicated my password was incorrect. I checked the 1Password Win 11 desktop app and saw the screen below. Note the password is "Password" and, while properly indicating the password was vulnerable, the field next to "Password" indicates the password is "fantastic." Of course, no one who values a service like 1Password would ever use the password "Password," nor did I. Even if someone attempted to use "Password" a target website would likely reject it.

I did immediately change the target website password, but I had to view my password history on 1Password to satisfy the target website requirements to provide the current password in order to change passwords.

However, I checked 1Password about a day later and once again saw that the password had been reset to "Password."

How did this happen? Could it also happen (or has happened) to one or more websites in my vault?

I have contacted 1Passord support, and they weren't able to answer my question. I offered to send system logs. Their response was that I had done something wrong. When I asked my request be elevated to a higher level of tech support, I was ignored.
