Thank you!In my case, I had mentioned given name followed by surname in the form.
In my application I put my parents and wife's name as <surname> <given name> and it went though and is being processed at consulate general. Sure, I didn't have to submit my parents passport copies but I did submit my wife's passport copy.
But for some reason they are extra picky with my kid's application and they require it to be<givenname> <surname>
