So you received derivative status 5 years ago from wife. Perhaps IO didn't have a copy of your marriage certificate in your case file which caused IO to question marriage status at the time ?
I just looked at my original I-485 case file which contained a copy of marriage certificate, but my wife's original I-485 did not have a copy of marriage certificate. I was the derivative recipient at the time.
It could be that you originally provided the marriage certificate when your wife applied for GC, but USCIS didn't include a copy of it in your case file thereby making the IO request it at interview.
I received derivative status 5 years ago form my husdand, my husbend got green card through H-1. I got a immigration visa from US consulate and submitted my marriage certificate to the interview officer, so I think they should have it.
