Hello, I have found out that whether sub-headers are included in a columnview table depends on org-tags-match-list-sublevels which I hope is a bug because it is unexpected and interferes with the columnview configuration. Please have a look at the attached file which demonstrates the problem. No configuration necessary, the bug manifests itself when emacs is executed with -Q. I was able to observe this with Org mode version 9.5.5 bundled with openSUSE Emacs 28.2 (when invoked as emacs -Q) but not with Org mode version 9.3 bundled with Emacs 27.1 bundled with debian bullseye. Thank you very much for looking at this, please consider CCing me when discussing the issue because I am not subscribed to the org-mode list.
