Why are S2 players labeled "Wild" in my roster?

Now that Season 2 is supposed to be S2 and Core players only, why is it that Captain Series Corbin Carrol has a S2 badge and Daniel Schneeman Tops has a S2 badge but they say "Wild" above them?

Because your squad is geared for Season 1 (has S1 by its name). Create a new squad for 2 or for in general.
