The following MWE illustrates:
--8<---------------cut here---------------start------------->8---
#+COLUMNS: %25ITEM %6CLOCKSUM{:}
* Goal 3
:PROPERTIES:
:ID: goal_3
:END:
#+BEGIN: columnview :hlines 4 :id goal_3 :maxlevel 3
#+END
** TODO Task 1
:LOGBOOK:
CLOCK: [2020-01-26 18:05]--[2020-01-26 Mon 19:16] => 1:11
:END:
Task body
*** TODO Subtask 1
:LOGBOOK:

:END:
--8<---------------cut here---------------end--------------->8---
Starting with `emacs -Q foo.org', place the cursor on the `#+BEGIN:
columnview' line and type `C-c C-c`. That produces a table (although
the entries are wrong):
--8<---------------cut here---------------start------------->8---
#+BEGIN: columnview :hlines 4 :id goal_3 :maxlevel 3
| ITEM | CLOCKSUM |
|-----------+----------|
| Goal 3 | 2:11 |
|-----------+----------|
| Task 1 | 2:11 |
|-----------+----------|
| Subtask 1 | 1:00 |
#+END
--8<---------------cut here---------------end--------------->8---
But then doing it again fails with the following (elided) backtrace:
--8<---------------cut here---------------start------------->8---

Part of the problem seems to be that `org-get-entry' manufactures
CLOCKSUM properties out of the CLOCK entries above, but
`org-put-entry' knows that that's a special property and refuses to
put it. But I think the major fail is in `org-columns--compute-spec'
which takes the property at face value and just passes it along. I
believe it needs to do whatever accumulation it is supposed to do and
set a text property to store the value in the headline, but that's
guessing on my part.
I saw this on Emacs SE (the above example is a simplified version of
the example in the post):
https://emacs.stackexchange.com/questions/55164/org-columns-error-the-clocksum-property-cannot-be-set-with-org-entry-put
and it has apparently been reported once before:
