[ARCHIVED] [LS] Gallery Sims from Cupid's Corner have high-pitched voices

I'm having a similar issue, I picked a male sim from Cupid's corner and had my sim go on a date with him. When the date started the male sim had a female voice, I took the Cupid's corner male sim into CAS and in CAS they had a normal male voice. I've left a link here to the video I made of it!

I'm playing with No Mods and have all the packs available.
