Do i need to Withdraw Approved Amendment to file a new Amendment

My Original H1b Petition was for New Jersey then i got an Amendment for California which got Approved and Stamping was Done on that, Now i will be travelling to US for the first time to Maryland Location so again my company is going to file for an Amendment for Maryland Location so in order to file for an Amendment do they have to Withdraw the Previous APPROVED Amendment of California ?

If Yes then will there be an Issue as my Passport would have Previous Amendment Petition Number and i would be carrying Recent Pending Amendment.

i have the same question ? can you help me what did you do ?
