Q: Apple Mail app not showing headers

The Apple mail app includes a preview pane below the summary of inbox contents.  It used to show a message with header fields called out by To:, From:, CC:.  Now it is not showing the field names, and not showing the To or CC info at all.  I can't find anything under View tab to change the display format.  Same problem if I display a message in its own separate window, there are no header field names and no CC field shown at all.  How can I get back to the old view format showing field names?  I am running OS 10.9.5.  Is there a way to reset the App to default settings, or to download a fresh copy of just Mail (not the entire OS)?

iMac, OS X Mavericks (10.9.5)
