I believe you mean the buffer-level does not override the
language-level.

I have no idea what could be causing the above, but it seems unrelated.

You can find the name of the original org-mode buffer by running the
following snippet of elisp within the edit buffer.

    ;; -*- emacs-lisp -*-
    (marker-buffer org-edit-src-beg-marker)

The `org-src-in-org-buffer' macro may be used from an edit buffer to run
elisp inside the code block, in the org-mode buffer of the edit buffer.
e.g., the following 

    ;; -*- emacs-lisp -*-
    (org-src-in-org-buffer (message "-->%S" (org-babel-get-src-block-info)))

Best,
