Hi Manuel,

Thanks for the feedback. I guess then it depends on some configuration
parameter or another. Did you see the customizations I posted? Does it
differ in any way from yours?

(setq gnus-face-1 'jao-gnus-face-tree
      gnus-show-threads t
      gnus-thread-hide-subtree t
      gnus-build-sparse-threads nil
      gnus-refer-thread-use-search t
      gnus-summary-make-false-root 'adopt
      gnus-summary-gather-subject-limit nil ;; 120
      gnus-summary-thread-gathering-function #'gnus-gather-threads-by-subject
      gnus-sort-gathered-threads-function 'gnus-thread-sort-by-date
      gnus-thread-sort-functions '(gnus-thread-sort-by-date))
