Why won't Keychain show me passwords I search for?

I don't know what's going on with my Keychain. I had to access my Apple ID to sign in, opened the Keychain, put Apple ID in the search window, and nothing whatsoever showed up!

And when I search for just Apple, I get hundreds of results, but even if I try to look through them all, I can't find it! What happened? This wasn't acting like this until very recently, probably since the latest OS update (11.6). I guess this is yet another bug from an update released before it's time.... smh
