Qwen/Qwen-Image-Edit · Not sure if it's error or the way it works

So basically it works great when I say as e.g., change this to that of anything. And after that it keeps the image same but just changing things which I have asked. But when I ask it to remove something particular from the image it would generate in o/p an image that is fully AI generated and clearly different from the original image I have provided and referenced it. Like it keeps the general idea of the what image is but it generates a deformed image like those generated by petty cheap AI models.
