Bug: Repeating tasks no longer appearing on future dates in the agenda [9.3.6 (9.3.6-17-g389288-elpaplus @ /home/gustavo/.emacs.d/elpa/org-plus-contrib-20200224/)]

[Gustavo Barros]

Hi All,

As of recently, repeating tasks are no longer showing up in the agenda 
for future dates. Below a minimal example of the issue:

Start "emacs -Q" and do some setup:

#+begin_src emacs-lisp
(package-initialize)
(setq org-agenda-files '("~/test/agenda.org"))
#+end_src

Where "~/test/agenda.org" contains:

#+begin_src org
,* TODO weekly task
SCHEDULED: <2020-02-29 Sat +1w>
#+end_src

Open the agenda: "M-x org-agenda RET a", navigate for future dates and 
notice only the first instance of the repeating task is shown.

I can narrow the emergence of the problem between the following 
org-plus-contrib versions.

Latest working: Org mode version 9.3.2 (9.3.2-8-g47b104-elpaplus @ 
/home/gustavo/.emacs.d/elpa/org-plus-contrib-20200127/)

First non-working: Org mode version 9.3.2 (9.3.2-24-g5c72d6-elpaplus @ 
/home/gustavo/.emacs.d/elpa/org-plus-contrib-20200203/)


Best,
Gustavo.
