14.7 HomePods not answering "Hey Siri"

I have several OG HomePods, and when I "Hey Siri" the one in my bathroom, it doesn't respond at all. The ones in the bedroom will answer the command. It's very weird. Even if I whisper the "Hey Siri" the top will light up, but the response comes from the ones in the other room. They aren't in stereo pairs. They aren't even in the same "room" in the "Home" app.

Not sure what's going on, but it's a bit weird. I'd love for Apple to get their "Home" app working correctly. My WeMo switches, and IKEA blinds keep falling out of HomeKit and getting "No Response" in Home, but work correctly from their apps. It seems like there's a problem with the HomeHub somehow. For me, that is the latest AppleTV, so it isn't like there isn't processing horsepower. Apple really needs to fix this.
