The psionic Vitalist class' level chart includes a Powers Known section, much like for the Sorcerer. PCGen is currently matching exactly that number. The problem with that is that the powers list is that number, plus whatever power is granted automatically by their 'method'. It's not too dissimilar to the cleric's domain spell, though they don't get to pick from two.
The flipside of this is that the power is selected automatically, and you shouldn't be able to get rid of it even though you can change (other) powers from day-to-day normally. The powers associated with each method are: Guardian – Biofeedback, Intercessor – Telempathic Projection, Mender – Natural Healing, Soulthief – Collapse.
