Why would Firefly add a derogeory word/ethic slur to my image when I ask for "a diverse group of multi ethnic people?"

Here is my prompt and image result. I do not appreciate the slur of “Coon” being added to the image on the left. Highly inappropriate and racist, Adobe!!! You are better than Grok.

Prompt:
Create a tax and business tracking collage image to be used to explain and article on real estate related business practices. The colors should be light blues and white and creams and images could include a computer, tax documents, calculator, cell phone, receipts, condo images, car, a diverse group of multi ethnic people looking at a house. Images can be mostly photos and a mix of illustrations.
