Text to Speech Installed Voices Not Working

I'm using Adobe Audition version 13.0.12 on a windows 10 machine. I've installed additional voices on my computer following the directions as stated on Microsoft's website. When I open up Audition only a few of them appear and only the female voices can be selected. I've tested all the the voices out in the speech settings on my computer and they are all there and functional. How do I get all these voice to appear in Audition?
