'Android Facebook Login invalid keyhash suspicious

I've been notified by Facebook support that login isn't working (though it's working on every phone I've tested), and I've triple-checked that in the developer setting for my app my debug and release keyhashes are there. I also use FirebaseUI for login.

They sent a screenshot showing a keyhash proving that my login "wasn't working" that showed the missing keyhash (the screenshot looks like this), but it doesn't match my debug or release keyhash. It seems kind of sketchy - am I missing something?
