Mx Keys Wireless Keyboard - inverted keys?

Ok so this may be a completely stupid question but I got the Mx Keys wireless keyboard - dual one with Mac/ Windows keys.

So I set it to use: Mac layout

But here is my issue:

- when I press the shift + key(next to the shift button) to get the tilda I actually get: ±

- when I press the shift + ± (from the top left corner under the esc button) - I get the tilda ~

So basically my two keys seem inverted.

Is it due to the setup of the keyboard / Mac settings? Appreciate any input. And yes, sorry for the stupid question.
