That was pretty much my thought too.

I've tried, when I originally reported, and now again, to pin this 
further down.  Alas, there is much in 'org-refile-get-location' I don't 
understand (in the sense of not understanding why certain things are 
being done). I also have much to learn with respect to 
'completing-read'. But I can provide an ECM to reproduce it.

- Start 'emacs -Q'

- Do an initial setup:
  #+begin_src emacs-lisp
  (add-to-list 'load-path "~/src/org-mode/lisp"); current master
  (setq org-refile-targets '(("~/org/test.org" :maxlevel . 2)))
  (setq org-refile-use-outline-path 'file)
  (setq org-outline-path-complete-in-steps nil)
  #+end_src

- Open file "~/org/test.org", with contents:
  #+begin_src org
  ,* Top heading 1
  ,* Top heading 2
  ,** Entry 1
  ,** Entry 2
  #+end_src

- Now, do some refile operations here. Inspecting 'org-refile-history' 
  will give us:
  #+begin_src emacs-lisp
  ("test.org/Top heading 2/" "test.org/Top heading 2/" "test.org/Top 
  heading 1/" "test.org/Top heading 1/")
  #+end_src

- Now, we reset 'org-refile-history' and start 'ivy-mode':
  #+begin_src emacs-lisp
  (setq org-refile-history nil)
  (add-to-list 'load-path ".emacs.d/elpa/ivy-20200211.1338"); current 
  Melpa
  (require 'ivy)
  (ivy-mode)
  #+end_src

- After some refile operations, the value of 'org-refile-history' is:
  #+begin_src emacs-lisp
  ("test.org/Top heading 2" "test.org/Top heading 2" "test.org/Top 
  heading 1" "test.org/Top heading 1")
  #+end_src

The difference is, as previously reported, the presence/absence of the 
trailing slash (the "extra" in terms of 'org-refile-get-location'). As 
far as I can tell, it is inconsequential to the working of the refile 
operation, but it did intrigue me.
