Found solution of this bug.
Due to the (outline-next-heading) method return nil value when current 
heading is the last heading in document. So it cannot work correctly 
during invoke (put-text-properties)

Temporary solution:
1. Add new headline at the end of org-mode document, like this:
* TODO hello
  :PROPERTIES:
  :Effort:   0:10
  :END:
* duplicated headline

2. Modify the source code of org-mode and then re-compile it.
This need to modify the method (org-refresh-properties) in org.el
change the following line:
(put-text-property
              (point-at-bol) (outline-next-heading) tprop p)
to:
             (put-text-property
              (point-at-bol) (or (outline-next-heading)
                                 (point-max)) tprop p)

Hope it works.
