Mistake in Season 3 DVD extras

Forgive me if someone has already mentioned this. On the season 3 DVD extras, where they show more extended scenes from KING LEAR, when they give credits at the end, Sarah Polley is listed as playing "Ophelia," rather than "Cordelia." Somebody screwed up, no? I wonder if that's something that can be corrected easily, when they manufacture further copies. I suspect not. Anyway, not a big deal, but surprising.
