Have you looked at ALL of the Normal Template settings in your Styles section? Some or all of your problems may be corrected by resetting those options. And when finished, don't forget to check the "New documents based on this template" box.
You might also want to revisit your Word Options settings. There's a lot to look through, but you may find that one or more settings have changed there too. And when finished, don't forget to scroll all the way down to the bottom to Compatibility option for: and select "All new documents."
