Maybe the method is wrong. For the superscript 1 with footnotes inserted in the paper:

1. The first scheme: delete the original superscript 1 and replace it with the superscript 1 automatically generated by the footnote. Disadvantages: The distance between the automatically generated superscript and the author's name is smaller than that set manually.

Option 2: Add a footnote at the end of this paragraph and leave the symbol blank.
