Hi,

I use the version cd6fa4c15e8e35afa6beb9e89ad3723fb82df091 (git sha) of
org-mode.

Let's say I have a file looking like this:

--8<---------------cut here---------------start------------->8---
#+CATEGORY: c
* foo
  :PROPERTIES:
  :CATEGORY: a
  :END:
** bar
   :PROPERTIES:
   :CREATED:  [2015-01-30 Fri 08:37]
   :END:
--8<---------------cut here---------------end--------------->8---

With the point on bar, `org-get-category' returns "a" while
(org-entry-get (point) "CATEGORY" t) returns "c". Notice that it returns
"c" even if the third argument is INHERIT.

This causes the strange behavior that I cannot set interactively the
CATEGORY property value to "c" with C-x C-c p.

The behavior is again more strange in the agenda, where the bar entry is
correctly shown with the CATEGORY "a" and trying to change it with
--8<---------------cut here---------------start------------->8---
C-x C-c p CATEGORY c
--8<---------------cut here---------------end--------------->8---
does nothing.

Is there a new way to interactively edit the CATEGORY or should
`org-set-property' tackle the special case of CATEGORY?

Best regards,
--
