A similar problem is complained about in the comments of lisp/repeat.el:

;; This works correctly inside a keyboard macro as far as recording and
;; playback go, but `edit-kbd-macro' gets it wrong.  That shouldn't really
;; matter; if you need to edit something like
;;   C-x ]              ;; forward-page
;;   C-x z              ;; repeat
;;   zz                 ;; self-insert-command * 2
;;   C-x                ;; Control-X-prefix
;; you can just kill the bogus final 2 lines, then duplicate the repeat line
;; as many times as it's really needed.  Also, `edit-kbd-macro' works
;; correctly if `repeat' is invoked through a rebinding to a single keystroke
;; and the global variable repeat-on-final-keystroke is set to a value
;; that doesn't include that keystroke.
