glitches with Award tickets and them displayed on the website happen frequently. I had a similar No Meal one last year when I upgraded to J via miles on a KL IAD/AMS. You get similar issues on upgraded flights with crediting your base miles.
The good thing: in case you do not get a meal you can get chocolates, candy and crackers at the galley during KL flights of that length
