Footnotes in File search in Chatgpt assistant

How can I prevent the assistant from adding footnotes to the sources in the output answer?

When I ask the assistant to search for information in my file, it provides the necessary information and adds a footnote at the end of the quote, such as “(1)” or, in a worse scenario, “(your_name_of_the_file.pdf)”.

I need the assistant to give clear answers without adding footnotes. I have already tried to type an instruction in the settings section that the assistant should not add footnotes, but it still does this.

Could you post the prompt snippet you are using to limit footnotes and file link so we can use it as a starting point for trying to sort it with you.
