Passport name mismatch, what do I do now?

I sat for my L1 during august this year. Today I have receieved a mail from the CFAI saying my name on my passport did not match the name I provided for registering to my exam. However they have mentioned that this issue will not affect me receiving my August 2022 attempt result. I checked my passport and the name on the CFAI website later and the name on my passport includes my father's name as well, which I did not write on the CFAI website. Anyone else have this happened with them? I am supposed to send a mail with the scanned copy of my passport with the name change request. Although they mentioned that it wont affect the results for my L1 results, its still a bit scary getting that mail
