A page's summary does not match the page's content
Sandvox has a feature which allows you to specify a custom summary for a page. WIth this enabled, the summary of the page is "disconnected" from the actual page content. The summary then does not update itself to reflect the page's content.
If you want custom summaries, you have to update them manually whenever you change the content of the page.
If you have changed your mind, however, you can always go back to automatic summaries.
To make a custom summary automatic again:
Keywords: summary, custom, page, update, reflect, match, different, control, click, right, control-click, right-click
