Pi Zero W Firmware showing Pi Model B+

Hi Sam,
I have use the full Raspbian image you have suggested and checked the model.

below is a screenshot of the result.

You can see clearly printed that the board is “Pi Zero W V1.1” but the model is stating “Raspberry Pi Model B Rev 2”

It does not have wifi/bluetooth so I am unable to do anything such as updates or connect to the internet.
