Strange Email message from MBL

My MBL is set to email me for events (like firmware upgrades, network status, etc).  A typical email looks like this: 

Following events are generated on your MyBookLive .

Event title: System restart

Event description: The system has restarted.

Severity:info

Event code:2001

Event time:07-24-2013 01:02:01 PM

Lately however, I’ve been receiving a very strange, uninformative email from the MBL once or twice a day.  It reads such:

Following events are generated on your MyBookLive .

 

Event title:???

 

Event description:???

 

Severity:info

 

Event code:

 

Event time:07-24-2013 04:31:44 PM

What to the question marks under Event Title and Event Description mean?  Why no event code?  Why is the MBL emailing me such inscrutable information?
