Voxos epic choir plays wrong samples for boys choir

As the title says, the "boys choir" plays the same samples as the "sopranos" in VOXOS epic choir from cinesamples. It used to work, but I didn't really need to use them ever. However, now they appear to be broken on version 1.0.11
I posted this issue on github where I was redirected to musehub support who redirected me here.

I have attached a video recording documenting the issue.
