Bluetooth Device Name in iPhone

Hi,

Does anyone have any idea why my forerunner has today decided that it is called "Neil's Pixel Buds Pro 2" in my iPhone Bluetooth device list? I saw this earlier and immediately deleted it thinking someone was trying to connect to my phone, but it then became apparent it was my Forerunner 965!

I have tried disconnecting and re connected, and also changing the name of the device through Gamin connect, but it is still showing as being called "Neil's Pixel Buds Pro 2". As I am sure you can imagine it is quite annoying as it was called Forerunner 965 until this morning.
