Zoe Leader is in the SP credits?

Hello,
I've seen many websites saying that Zoe Leader was one of the additional voices in Simba's Pride, and this leads some people to conclude that Sarafina appeared somewhere in the movie.
However, I just had a look at my SP DVD and scrolled through the credits looking for her name...and I couldn't find it anywhere. There are two sections titled Additional Voices, and Zoe Leader isn't listed in either. To make things even more suspicious, look at the SP credits on IMDB. Zoe Leader's name is there, but the field where her role would be listed is blank.
Was Zoe Leader simply not credited, or was the fact that she was one of the voices in SP never really a fact to begin with?
