org-ref breaks org-repair-export-blocks

Consider the following

#+BEGIN_SRC elisp
(require 'package)

(package-initialize)
(require 'org-ref)
(defun org-repair-export-blocks ()
  "Repair export blocks and INCLUDE keywords in current buffer."
  (interactive)
  (when (eq major-mode 'org-mode)
    (let ((case-fold-search t)
	  (back-end-re (regexp-opt

	 (while (re-search-forward include-re nil t)

After evaluating the elisp source block, org-repair-export-blocks
doesn't repair the LATEX block. However, (require 'org-ref) is commented
out, org-repair-export-blocks does its job.

What seems to be happening is those blocks are no longer special block, but
instead an export-block. If you change special-block to export block, then
it works for me with org-ref loaded.

I don't know why (or even how) org-ref would be changing that though.
