iphone password app won't open without face

My iPhone is set to require face-id or a passcode to unlock, but none of my apps are locked with face-id - not even the Passwords app. As a test, I had a family member try to open apps with passcode only. All apps but Passwords opened with just the passcode. For Passwords the passcode entry screen will eventually appear after several failed attempts, but after entering the correct code, a message appears stating that face-id is still required. This is contrary to the message that appears at the time of setting the "require face-id" option for any app, which states that either face-id or passcode will open the app. I want family members who know the unlock code to have complete access to any locked apps, and I understand that I can add them to face-id (they declined), but I think that if the instructions state that a locked app can be opened either way, then it should. Is this a bug?

iPhone 11, iOS 18.3.2
