Big time incompetent. They are constantly reconning, and seem to have a terrible case of too many cooks making one dish. I've unfortunately read quite a few Christie Golden books since her Star Wars work was mixed in with the overall storyline of the franchise at the time, and hers were straight up garbage every single time.
It seems fairly obvious that there is no one in overall control of the storyline, or at least no one that is interested in actually doing their job. Leaving the story with a massive number of contradictions and the retcons I mentioned before.
