About footnotes

[Susan29839210pugn]

Dear people, I have a problem when creating a pdf from a word document. A 'fly poop' appears under all the numbers of the footnotes in the text. How can I prevent this?

I would check my document in Word. It does not exactly look like a fly poop to me.

For the footnote 7, the information reads 6F.

I was not able to "underpress" it, after disabling all possible options in the PDF plugin of Acrobat Pro (latest version)-> Win10/11, from Word 365.
