It seems as if something is preventing you from saving to Normal. Try opening the Normal template as a document and save the formatted AutoCorrect entry directly to that file (via File tab | Options | Proofing | AutoCorrect Options). Save and close Normal.
To open Normal as a document, do the following: From within Word, press Ctrl+O. In the Open dialog box, click "Templates" in the left pane. Click Normal.dotm and then click the Open button.
If the above works (which it should), the next step is to figure out why you cannot save properly to Normal.dotm.
