Here is described the problem:

--8<---------------cut here---------------start------------->8---
ange-ftp-reread-directory

Reread remote directory DIR to update the directory cache.
The implementation of remote FTP file names caches directory contents
for speed.  Therefore, when new remote files are created, Emacs
may not know they exist.  You can use this command to reread a specific
directory, so that Emacs will know its current contents.
--8<---------------cut here---------------end--------------->8---

So actually when some files have been copied or removed, one should
reread the ftp directory to update cache.

This should been done automatically isn't it?

I have fixed this in helm by doing this before listing a directory:

--8<---------------cut here---------------start------------->8---
  ;; Always reread ftp directory, otherwise we will never be aware
  ;; of new or deleted files.
  (when (eq 'ftp (file-remote-p directory 'method))
    (setq ange-ftp-ls-cache-file nil)
    (remhash directory ange-ftp-files-hashtable))
--8<---------------cut here---------------end--------------->8---
