Your pictures appear flipped though according to your description. I see an off the ground Eliza getting hit for 16k and an in the air Eliza getting hit for 19k, which would appear to be correct.
We are aware though of DAF not appearing to work against all fighters though, meaning players will launch > Juggle > DAF and not get the additional damage, because depending on the opponent, they may hit the ground before getting hit with the BB. Right now that's a nuance of using the move but I've been pushing to hopefully have it work consistently across all fighters, though no promises as to when that'll get looked at by the design team.
