[Sorry for not replying in-thread...]
Hi All,
after updating I'm getting the same result, but I could not reproduce it
even with my org-config until now.
The culprit seems to be in org-agenda.el, ll. 6098 ff., in
org-agenda-get-deadlines:
((eq org-agenda-skip-deadline-prewarning-if-scheduled
'pre-scheduled)
;; Set pre-warning to no earlier than SCHEDULED.
(min (- deadline scheduled) org-deadline-warning-days))
So it needs an item with deadline *and* scheduled time, and the
'pre-scheduled setting of the config var
org-agenda-skip-deadline-prewarning-if-scheduled.
Subtracting "scheduled" fails: every date in the procedure is an
integer, scheduled is still the raw string from the item. At the
moment, I am too tired to figure out why that is, sorry. Hope this is
still of some help.
