[O] editing orgmode code blocks always indents content..anyway to stop this?

[Xebar Saram]

Hi all

i have this weird behaviour where when sometime i edit org code blocks the text moves (i guess indents) automatically so i start with this

#+BEGIN_SRC emacs-lisp  :results none

(require 'gnus)

(require 'nnir)

#+END_SRC

and the text switches automatically to this:

#+BEGIN_SRC emacs-lisp  :results none

    (require 'gnus)

    (require 'nnir)

#+END_SRC

is there a setting to disable this?

best
