The Grid Surface Outside/Inside settings control the Surface setting of the Mullion.
But as I see it, the Frame Surface Outside/Inside parameters control the Surface settings of the Frame around the leaf, the Frame of the Transom and the Frame of the Sidelight, probably because they are generated as one geometry.
Are you sure this was possible to set separately in AC17?
The surface settings seem very similar to me for this Door type in AC17 and AC19 and I cannot set Surface separately for the Transom and Sidelight in AC17 either.
