since you’re getting questions about this, thought I’d clarify: the categories are for lead actress (Angelique), supporting actress (Maca), and then “experienced” actress (Raquel), and young actress (Barbara). AFAIK you cannot be nominated for multiple. Other novelas did have multiple people in the same category. Barbara defaults to the last category because she wasn’t billed high enough for the first two and doesn’t have the repertoire for the third.
Oh, okay, thanks for explaining! Though didn’t Alexis Ayala get two?
