PLEASE DONT PANIC.
Wait for their correspondence assuming they will ask you for the missing documents after checking their records and assuming they find your previous application
Be proactive and send them the PDF of the SINP correspondence mentioning your Passport number as that is the one which should be unique and you can just hope that they are able to keep your missing doc in the same package
@ OK Ram i have made up mind, as they say if it ain't broke don't fix it.
