Change Auditor Event capture of Exchange Mailbox Export to *.pst in Exchange Admin Center shows Mailbox GUID in lieu of name (4318355)

An administrator observed that if an Exchange Mailbox is exported to *.pst from the 2013 Exchange Admin Center Change Auditor captures the Mailbox name as a GUID (figure 1). This condition is also reflected in the Windows Event Viewer MSExchange CmdletLogs well, (figure 2).

However when the same event is executed in the Exchange Management Shell (New-MailboxExportRequest), the mailbox name is recorded correctly in both Change Auditor and the MSExchange CmdletLogs, (figure 3 and 4).
