"Don't change my ethnicity" would do nothing, as these programs can not get descriptions from images, only create images from descriptions. It has no idea that the image contains a woman, never mind an Asian woman. All it does is use the image as a starting point to create a "professional photo". There absolutely is training bias and the fact that everyone defaults to pretty white people in their 20-30s is a problem. But this is also using the tool badly and getting a bad result.
