That means, there is at least one matching item "root@black-diamond",
but no item "ethan@black-diamond". I said it already, but again: these
are labels for the items. They don't tell us which properties are used.

Yes. For sudo, doas, and alike.

If we want to understand better, we must know which items you
have. Please try the following: "M-x secrets-show-secrets". This will
show you the collections, in my case I see

There must be two items with the label "root@black-diamond", according
to your obeservations. Click on both, and show the contents. I have done
this for the "albinus@ford.local" example:
