Sure. I'm able to reproduce this by running emacs -Q and evaluating the following:
(setf org-agenda-files '("~/org")) (setf org-todo-keywords '((sequence "TODO(t!)" "NOW(n!)" "WAIT(w!)" "|" "DONE(d!)" "CANC(c!)"))) (setq org-blank-before-new-entry '((heading . nil) (plain-list-item . nil))) (setq org-capture-templates '(("t" "todo" entry (file+olp+datetree "~/org/superbug.org") "* TODO %?\n%U\n%a" :time-prompt t))) Then, I hit M-x and run org-capture, and select "t". Pick a date in the future (or the past, so long as it's the first capture for that date), and capture. This results in a datetree with a blank line in between the date and the captured entry, for example: *** 2025-05-22 Thursday **** TODO test capture [2025-05-22 Thu 00:00] [[file:~/.config/emacs/test-org-blank-init.el]] Let me know if you can reproduce, else this is some weird behavior specific to my machine... - critbase
