Apple TV Remote changes Sony TV input when clicking Back or Menu button (2nd question)

Identical issue/TV to the original post found at: Apple TV Remote changes Sony TV input whe… - Apple Community

I have my Apple TV labeled “Living Room”, and my Sony A80J seems to think it’s on input HDMI 4 under the Bravia Sync settings before I restart my Apple TV, where it then resolves the issue with the Back/Menu button incorrectly changing inputs and realizes the correct input it’s connected to, HDMI 3.

As the OP suggested, I feel this is a software issue since a simple Apple TV restart resolves the problem. It’s interesting to note (and I don’t think it’s a coincidence) that we both have exact same TV and problem with our Back/Menu buttons resorting to the incorrect input.

Any update would greatly be appreciated.

Thanks!
