I mostly appreciate that this translation makes it clear that the Princess was a "Hero" and didn't have a Hero
Again, you seem to be quite confused about who written what, and what does that mean. Chapter 9 ended with a single sentence in the whole page: "She is a hero". Pretty clear if you ask me. Chapter 10 starts by elaborating on it, saying that people are bestowed with a job at birth, that this job is random and that it is almost impossible to change; it then explains that, despite the appearance of prestige the "hero" job has, the "gift" she was given was actually full of thorns, and she had to act cunningly in order to survive.
How do you get that "she have a hero" from all of that, is beyhond me.
