Multiple image prompt collapses into a single collaged image

I found the same questions on Reddit

I used to build a front-view & back-view in a single front due to its consistency and efficiency. But lately ChatGPT ignores my prompt although I explicitly stated “No collaged image”, “no collage”, etc.

Instead of getting two images. I am getting one with split-screen.

Is there any bullet-proof prompt to avoid this? or this is a known bug?
