The Google Wallet design requires the organisation name of the issuer to be displayed at the top of the pass next to the logo.
As default this name is pulled from the organisation of the PassKit account owner, which is set here.
However, you may want to change the default organisation name if you are issuing across different brands, or on behalf of another organisation.
This can be done by navigating to the design settings when using the pass designer.
Example after making the change.
