I cannot reproduce it. Here's my test setup:

I have created a new directory /tmp/tmp with the following files:

--8<---------------cut here---------------start------------->8---
# ll /tmp/tmp
total 8
-rw-r--r--. 1 albinus albinus 47 May  9 13:27 xxx
-rw-r--r--. 1 albinus albinus 47 May  9 13:27 yyy
# cat /tmp/tmp/*
Host xxx-63359
     Hostname xxx-63359.invalid
Host yyy-63359
     Hostname yyy-63359.invalid
--8<---------------cut here---------------end--------------->8---

I have created a file /tmp/tmp.el with the following contents:

--8<---------------cut here---------------start------------->8---
# cat /tmp/tmp.el
(use-package tramp
  :config
  (with-eval-after-load 'tramp
    (tramp-set-completion-function
     "ssh" (append (tramp-get-completion-function "ssh")
                   (mapcar (lambda (file) `(tramp-parse-sconfig ,file))
                           (directory-files
                            "/tmp/tmp/"
                            'full directory-files-no-dot-files-regexp))))))
--8<---------------cut here---------------end--------------->8---

Then I have tested

--8<---------------cut here---------------start------------->8---
# emacs -Q -l /tmp/tmp.el -f icomplete-mode
# emacs -Q -l /tmp/tmp.el -f fido-mode
--8<---------------cut here---------------end--------------->8---

After typing 'C-x C-f /ssh: TAB' I have seen the candidates 'xxx-63359:'
and 'yyy-63359:', in both tests.

Looks like there is something odd with your config? Could you please try
my recipe, whether it also works for you? Then you can add step by step
your config, and check what's wrong?
