Nano-banana-pro unnecessary centers image

I am using the current Nano-Banana-Pro API. I am making a project in Blender, and for that, I want it to fill in a black square and then make a background in the white region. It does that mostly correctly. However, the problem is that it tries to center what it has filled in the black square. This is obviously an issue. For now, I am using this prompt:

"The provided image is a layout mask with a black square on a white background. Follow these rules strictly:\n"

    "1. IMPORTANT: The black square defines the exact position of the subject/ center point. "

"Replace the black square with the subject drawn small and centered within it. "

"Do not shift the subject above, below, or outside the black square.\n"

"2. Replace the white background with a seamless background that fills the entire canvas from edge to edge.\n"

"3. The background must flow continuously through both the black square area and the white area.\n"

"4. Do not include any text, words, letters, numbers, logos, or watermarks.\n"

Have other people also encountered this problem?
For refrence this is the image I also sent to the API.
