You cant update passport in the system while an application is in progress. You would need to contact CBP to update or wait till interview.
Till then you can activate the GE machine by looking up your document. Simply select the having problem with document option. Follow the steps and it'll pull up your membership. I was having issue getting my passport to update in system and officer told me this was work around.
