Source:Path of Shadows, Nightblade arts not showing

In the Path of Shadows by Ascension Games. The Nightblade class, once the path "Path of the Twilight Veil" is chosen, Nightblade Arts specific to that path are not showing. These are:

Controlled Distortion
Irresistible Shade
Shade Inoculation
Shadow of Doubt
Shrouded Casting

They are listed in the pos_abilities_class.lst file, but not appearing in PCGen.

Thanks!
