Just telling you what your own GCMS notes say.What I am saying is that: How the official knows it was a marriage certificate from US if the file wasn't sent? Of course the file and the certificate were sent!
You are asking me if I have sent the file with the marriage certificate. Of course I sent, otherwise how the official would know that the certificate was from the US? And in case you are wondering what I've sent, it was the official marriage certificate, with official stamp and seal, signatures, in an anti-fraud paper, clearly saying Marriage Certificate. It's was not an affidavit, was a marriage certificate.
Also telling you that your PR application was not refused because of where the marriage took place but because, for some reason likely connected to a screw-up on their end, IRCC does not believe it has a copy of the certificate.
While I get you feel that you need to insist that the words that say "marriage certificate not provided" must mean "marriage not registered in home country," there's only so much room for interpretation from the actual notes.
