How to Prevent Repeated Stock Photos in API Image Generations Across Different Themes and Styles

Strange outcome I'm having with API generations - for some reason the same stock photos keep appearing in generations with different themes and image styles selected - any idea how i can keep these same images from popping up? Seems like they're in @75% of the gestational from this prompt - two links for examples https://gamma.app/docs/Your-Home-Your-Options-wmtooclbtzxufr4?mode=doc and a 2nd one https://gamma.app/docs/Your-Home-Your-Options-Your-Best-Outcome-9meenchkrs54fsg?mode=doc One more: https://gamma.app/docs/Your-Home-Your-Next-Chapter-oxxmjgh0yfeocec Im familiar with these images - I've used them in other places but not in gamma. Multiple users across the country use our api for generation and some get these images pulled in, some do not. Just have no idea how they're getting in.
