All scheduled recordings suddenly gone

As of this evening, ALL of our scheduled recordings, both series and singles, are gone.  The DVR had them last night as we checked for our weekend recordings before we turned off the TV for the night.  This evening, Friday, September 9th, the entire scheduled section is blank on the DVR, the XFinity phone app, iPad app, and web site (https://www.xfinity.com/stream/).

What would cause this and can it be undone or do we need to go through and re-schedule every single recording we set up over the past few years?
