I was able to reproduce this, and here are my findings as well as a
reproducible configuration with only a few settings.

=test.org= file:

#+begin_src org
* TODO First

* TODO Read book
SCHEDULED: <2021-06-15 Tue +1d>
#+end_src

Start emacs -Q and open the test.org file.

Go to the 'First' entry, and do C-c C-t. This adds an a timestamp record
(this does not happen with 9.4.4, not sure if the default behavior has
been changed).

Changed test.org file:

#+begin_src org
* DONE First

- State "DONE"       from "TODO"       [2021-06-14 Mon 23:23]
* TODO Read book
SCHEDULED: <2021-06-15 Tue +1d>
#+end_src

Now, load this configuration:

#+begin_src elisp
(add-to-list 'load-path "~/src/org-mode/lisp/")

(setq org-todo-keywords
      '((sequence "TODO(t)" "|" "DONE(d!)")))
#+end_src

Open the test.org again, and go to the "Read book" entry, mark it done
with C-c C-t. Now, there are two timestamp changes getting recorded.

#+begin_src org
[…]
* TODO Read book
SCHEDULED: <2021-06-16 Wed +1d>
:PROPERTIES:
:LAST_REPEAT: [2021-06-14 Mon 23:26]
:END:
- State "DONE"       from "TODO"       [2021-06-14 Mon 23:26]
- State "DONE"       from "TODO"       [2021-06-14 Mon 23:26]
#+end_src
