It might just be an unwanted side effect of something in OP's .emacs.
For example I saw the code below on emacswiki.  It would cause these
symptoms and a user may not connect the two without understanding the
connection between add-mode-abbrev and local-abbrev-table.

(defun sql-pre-abbrev-expand-hook ()
  ;; Allow our abbrevs only in a code context.
  (setq local-abbrev-table
	(if (sql-in-code-context-p)
	    sql-mode-abbrev-table)))
