Я решил эту проблему, изменив org/lisp/org-footnote.el
(defconst org-footnote-re
;; Only [1]-like footnotes are closed in this regexp, as footnotes
;; from other types might contain square brackets (i.e. links) in
;; their definition.

;; `org-re' is used for regexp compatibility with XEmacs.
(concat "\\[\\(?:"
;; Match inline footnotes.
(org-re "fn:\\([-_[:word:]]+\\)?:\\|")
;; Match other footnotes.
"\\(?:\\([0-9]+\\)\\]\\)\\|" ; <-------- comment out this line
(org-re "\\(fn:[-_[:word:]]+\\)")
"\\)")
"Regular expression for matching footnotes.")
(defconst org-footnote-definition-re
(org-re "^\\[\\([0-9]+\\|fn:[-_[:word:]]+\\)\\]")
"Regular expression matching the definition of a footnote.")
