How to Add Dragon Style?

[Pretender]

So, I've recently bought both Legacy of Dragons and the Ranger pack. I thought that I'd be set to go. To my dismay, though, despite having Ultimate Combat, I don't seem to be able to add the Dragon Style feat to my character sheet. I can tick Ultimate Combat on or off, so I know that I have it. So how do I add the feats in the book to my character sheet? What am I missing here?

EDIT: The issue appears to be that Scaled Fist asks you to provide a workaround by which it will allow you to select dragon style.
