Thank you very much.
I think maybe they're two different people.

Barbara Scott (IV)
TMDb https://www.themoviedb.org/person/1040034-barbara-scott
IMDB https://www.imdb.com/name/nm0459788/ Barbara Scott (IV) (1946–1995) - Actress

Barbara Scott (III)
TMDb https://www.themoviedb.org/person/1534509-barbara-scott
IMDB https://www.imdb.com/name/nm0778864/ Barbara Scott (III) - Costume and Wardrobe Department | Costume Designer | Actress

Could you check the credits and "return" the wrong ones?
I suppose this image is not Barbara Scott (III) https://image.tmdb.org/t/p/original/xwV7KhmVkDsSimpF92Xdi89EbJ0.jpg

Edit: I think I got the 2 credits back.

TIP: If you want to force the line break, click Space 2 times and then click Enter. Just Space > Space > Enter.
