Connected to ONLY ONE device (air pods 4) but on the control center is indicated as if i am connected to 2 devices

Hi,

only in the control center, as soon as I connect to my air pods 4 (with ANC),

I see that I'm connected to 2 devices, but when I go on the Bluetooth list I can see that I'm connected only to 1 device.

This happens only with those AirPods 4.

I've already open a ticket with apple and reset the connection/Wi-Fi setting but nothing changed.

Thanks for the help.
