Hello,

Can anyone reproduce this?

Say I write the following in my agenda org file:

* Weekly meeting
  <%%(diary-cyclic 7 9 10 2021) 9:00-10:00>

Invoking org-agenda with a (org-agenda-list) does not show the 
item, whereas scheduled diary sexp or plain timestamp works fine:

* Weekly meeting
  SCHEDULED: <%%(diary-cyclic 7 9 10 2021) 9:00-10:00>

or

* Weekly meeting
  <2021-09-10 9:00-10:00 +1w>

emacs version:

GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 
3.24.27, cairo version 1.17.4) of 2021-03-27

-- 
Best,
Yuchen
