Phone: "Greeting & Leave Voicemail Instruction" keeps playing a DELETED audio instead of new one

I had a few possible audios recorded and they seemed to be ok. And then I tried the default. Nope. I'll use one of my own.

So I deleted the existing audios I'd done -- nothing at all showing on that screen. And then I recorded a new one. It plays back just fine there on the Settings page. And it's the ONLY recording showing on that page that shows the audios you've recorded.

But when I call the phone number, the OLD and deleted audio keeps playing. And worse, immediately after the deleted one plays, the default (and very loud) "We are sorry ..." message plays, too.

How on earth can I fix this? Thanks for any help.
