Org Mode: Issue with repeated tasks

Question

I started getting this issue with repeated tasks now. Assume I have a task like this:

** TODO test task
   SCHEDULED: <2013-11-12 Tue + 1m>

I want to close and schedule it for next month. So I do C-c C-t. After doing this I get the following:

** DONE test task
   CLOSED: [2013-11-12 Tue 17:10] SCHEDULED: <2013-11-12 Tue + 1m>
   - CLOSING NOTE [2013-11-12 Tue 17:10]

Issues:

1. As you can see, the scheduled date is same as the old date.
2. TODO has changed to DONE. It should stay in TODO with the new scheduled dates.

This issue started appearing recently. Any help is appreciated.

Answer 1

Remove the space between + and 1m.
