Boarbarian Skill Book Issues

At first I thought Boarbarian was a very useful new monster.
Now I've learned it is just another illiterate little piggy.

When trying to teach Boarbarian any new skills through Skill Books I receive a pop-up message saying " There are no skills available for this monster. "

My most recent attempt was with an advanced skill.
The book is titled
Poison Leaves
( for Epic and Legendary Monsters )
Boarbarian is an Epic Monster.
Please fix this issue so we can teach all our little piggies how to smash and bash!!!!!

Boarbarian can't learn any new skills, he's designed that way .
Most people get him just for that +1 monster count that brings them one step closer to Leviathan.

Oh, well then. Lol
Thank you for your help!
