Hmmm. Could it perhaps be because the quest is at stage 0?
Create blank stage 10, and then manually set it to 10 in game and see if they fill. Also, how the hell are you seeing that data that you posted for the outcome? That would be so useful...
EDIT: Another thought. Create a player alias just for the sake of testing, and set it to "specific reference" PlayerRef. See if it fills. If it does, the issue is possibly because your references don't actually exist. That is to say, they aren't in the game world yet. (Hell, you could try placing one of them inside the world to test it if you prefer.)
