This seems to be a general problem with the tool it only applies effects to faces and nothing else rendering the entire thing useless in my opinion (unless you need AI to help you create really awkward photo art where people's faces look normal but the surrounding photograph does not). I just don't understand why they are charging money and not communicating that their AI model only works on faces. Finish the product before selling it.
Unless I'm just wrong about this but if so, and if the solution is in some sort of setting I'm just not seeing the user interface needs to be reevaluated I've spent way more time than is reasonable trying to infer what the issue is because customer service on any channel they suggest is just AWOL.
