At this point, I'd recommend reporting this issue to Kobold Press - the links to the bug reporting addresses for each company are here:

I'm looking at the code, and the only ways to get the incantation tab to show are three things - the Rune Mastery feat, a class ability called Shadow Traveler (looks like it's for a class named Twilight Envoy), and a class ability called Revelation of Runes (looks like the class is Doom Croaker).
The incantations are implemented, but they were not set up as spells, and I'm afraid that I'm not certain what design KP had in mind for how users were supposed to add these.
An alternative to entering them all would be to create a mechanic that bootstraps the cfgKPRunes configurable - that should allow that same table to show up on any character.
