Siri - Apple TV shuts off other TV

[chefwong]

Current topology

ATV - Connected to Receiver-TV connected to EARC
Telling the Remote (Siri, turn off Apple TV) does turn off the TV and Receiver.

However, this has creeped up lately and I have not idea what is happening.
If another room is watching TV on a STB feed (FIOS) but there is also a Apple TV connected to TV

When the room in the 1st part of this post is told to turn off Apple TV, it also turns off the TV in the other room

It never has behaved this wey in the past but just put 1+1 together when I happen to notice the other room getting turned off

When using Siri to turn off the Apple TV, specify the full name, for example, Living Room Apple TV.

In the past.....at least up until maybe 6 months ago , when using Siri via the ATV remote to turn off TV, it would only turn off the TV in which the remote was connected:married to.

I kinda:wanna say this just started around 6 months ago....but I did not pick up:confirm it was happening until just recently, the kiddos was like the TV turned off while it was still on in the other room
