Emacs 24.5.1, Org-mode 9.1, Windows 7

If I have task like this:
* Spring break
   SCHEDULED: <2018-03-30 Fri>-<2018-04-06 Fri>

I would see "Spring break" listed in the daily agenda for each day between
the starting and ending date in the "SCHEDULED" line. However, the exported
".ics" file only puts one entry for the starting date, which neither
correctly reflects the task nor be consistent with the daily org agenda
view.

Thanks for looking into it.
