Dalle-3 API always including additional writing instruments or hands when prompting for style

Hi, there:

I am confused by the dalle-3 api when it creates simple entity, like carrot, banana, the generated result always contains drawing pencils, or a hand drawing the entity. even if I have added instruction “not to generate drawing-pencils”, it still doesn’t work.

However, the same prompt would be OK if I use the Dalle in the chat portal.

Any idea?

The generated output is:
