Layout disappears, no title showing up

[Paulo Jorge de O. C. de Matos]

Hello all,

Here in my Carbon emacs I have in .gnus.el:
(defun sdl-gnus-summary-line-format-unicode nil
  (interactive)
  (setq gnus-summary-line-format
        (concat
         "%0{%U%R%z%}" "%10{│%}" "%1{%d%}" "%10{│%}"
         ;"%9{%u&@;%}" 
         "%(%-15,15f %)" "%10{│%}" "%4k" ;"%10{│%}"
         ;"%2u&score;" 
         "%10{│%}" "%10{%B%}" "%s\n"))
  (setq
   gnus-sum-thread-tree-single-indent   "◎ "
   gnus-sum-thread-tree-false-root      "◯ " 
   gnus-sum-thread-tree-root            "● "
   gnus-sum-thread-tree-vertical        "│ "
   gnus-sum-thread-tree-leaf-with-other "├─► "
   gnus-sum-thread-tree-single-leaf     "╰─► "
   gnus-sum-thread-tree-indent          "  ")
  (gnus-message 5 "Using ascii tree layout with unicode chars."))

(sdl-gnus-summary-line-format-unicode) 

interesting issue is that the subject of the post only shows up in the
root but not on the following posts of the same thread. Why? 

Moreover, when I enter a group the layout doesn't show up. For it to
show up I need to enter a message. Any reason why this is happening? I
was expecting the layout to show up immediately after I enter the
group. Any ideas?

Cheers,
