Hello,
Starting with version 9.4.6, state logging through a per-keyword marker `!' produces duplicate log entries on tasks with a repeater. A minimal test configuration to reproduce the issue is: (setq org-todo-keywords '((sequence "TODO" "DONE(!)"))) Then, creating a task with a repeater: * TODO Test Task SCHEDULED: <2021-06-04 Fri .+1d> And marking it done yields: * TODO Test Task SCHEDULED: <2021-06-04 Fri .+1d> :PROPERTIES: :LAST_REPEAT: [2021-06-03 Thu 19:58] :END: - State "DONE" from "TODO" [2021-06-03 Thu 19:58] - State "DONE" from "TODO" [2021-06-03 Thu 19:58] Instead of: * TODO Test Task SCHEDULED: <2021-06-04 Fri .+1d> :PROPERTIES: :LAST_REPEAT: [2021-06-03 Thu 19:58] :END: - State "DONE" from "TODO" [2021-06-03 Thu 19:58] I have done some debugging and testing. The first commit in which I was able to reproduce the bug is c670379adfbdc4883d3cfa230289fd2829993265. This commit changed the behavior of `org-add-log-setup' to call `org-add-log-note' directly (instead of just adding it to the `post-command-hook') when logging only a timestamp and no note. The problem is, that with a repeater when enabling logging through a `!' marker, `org-add-log-setup' is called twice: Once by `org-todo' directly and once by `org-auto-repeat-maybe' resulting in the two state log entries.
