That's definitely a bug from using an old save because she has the "Draconic Envoy" class when it should be Martial Maiden. I recall earlier versions of the game had her character slot use Draconic Envoy class, something I experimented with during the initial game development before the 4th player member actually became playable. I suppose that if you're using an earlier save, she got stuck with the old class too that has those whacky move slots.
You could restart the game from scratch, or if you wait a bit I can upload an hotfix that stealth-changes her class to Martial Maiden when she joins and at the main space healing spot.
