Soulknife extra damage?

[Bonkon]

Good Day All :)
I have a player that created a Soulknife (Using the Character Wizard) and it populates an effect on the action tab for:
Psychic Blades; DMG: 2d6 psychic
I do not see anywhere in the description of the class or specifically the Psychic Blades ability that gives this effect.
Can anyone please direct me to where this is usable by the Soulknife? If not can we have it removed from the automatic additions for the archetype?

Thanks :)

Edit: And now that I look at in copy/pasted here, shouldn't it have a comma between the 2d6 and the damage type?

I'm not seeing this addition to the effects tab. Are you using any extensions? Does this happen in a new campaign without extensions?

I should probably also ask what level was the character. I only made one to level 3 to test.

Good Day Zacchaeus :)
SMH..I never would have dreamed an extension could create a whole new effect on an actions tab, but apparently one does!! I have not dug any deeper than creating a char in a new campaign but it seems to be just that! I hang my head in shame. :confused: :)
And it was just a level 3 for a one shot.
Thanks for the quick reply! :)
