It seems as though updating the email schedule for an email report doesn't update the task timetable for that report.

For example, if we create a new scheduled report with the schedule as Monthly:

The task timetable sets the time/date that it will next run, in this case the first day of the next month (The report just created here has an ID of 8):

But if this report is updated to a different schedule, for example Daily:

Then the task timetable is not updated with the correct next date (Even after running a normal core:archive to let scheduled tasks run like normal):
