OCI application for new passport

[Brit_ind]

Dear forum members,
Greetings to all.
My 5 year old son is a OCI holder on his first British passport.
He now has a new passport after 5 years age and I am in the process of applying for OCI for the new passport...cant believe I have to do this till my kids are 20 years old!
I have completed the Part-B of OCI- Application and have uploaded the necessary documents.
The OCI Miscellaneous Registration Form however mentions our previous address and not the current one.
I tried to complete a fresh application for change of address, but the option to change the address is not possible, as that first British passport is no longer valid.
I am unable to select multiple miscellaneous services like change of address and change of passport at same time.
I am not sure if anyone has been through a similar situation and any advice will be deeply appreciated.
Regards,
