Home app controlling wrong room for different command

[TomNB]

Everything has been working fine for years. A few days ago, Google Home started controlling the wrong room.

For example:
I can say "Turn on the Living Room Lights" and the Living Room Lights will come on, but when I say "Turn off the Living Room Lights," they turn off the lights in a different room, and the display will show the other room being turned off.

All devices are still set up in the correct rooms. Everything looks okay in the app.

Sometimes a simple reboot of devices is helpful, making sure the mic is clear and clean, and speaking clearly to the Google home.   Also, what is the name of the other room it's controlling, is it similar to living room lights?  Try to give names that phonetically sound different so Google does not get confused.   

Not saying user error, just working through what could be the issue here.

We're tried the commands through various devices. The rooms don't sound much alike. It's never been a problem before. It's very consistent. It understands "turn on the living room lights" just fine, and consistently turns off the bedroom lights whenever we say "turn off the living room lights", while displaying "bedroom lights" when we use the Hub.
