Without checking through the entire list I gather it is an issue between them and the score provider likely down to the code/rule for players with the same surname and first initial, since I am unsure if there any examples of players missing that do not fit the above criteria.
I don't actually know, I made the trade when the projected lineups had Lively starting and Giles not. When the lineups were confirmed, Lively didn't actually start after all.
