Hello Christian,
Thanks for reporting but I cannot reproduce the bug with the org and emacs version below. Org mode version 9.5.3 (release_9.5.3-467-g2bd34e @ /home/djj/src/org-mode/lisp/) GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.24) of 2022-01-16 Can you please let me know which version of org-mode you are actually using? Ihor, many thanks for checking.
