Maybe there is another task. This Powershell command (run as admin) will list the scheduled tasks that ran in the last 24 hours. See if the run time of a task matches (or is close to) the defrag event time.

Get-ScheduledTask | Get-ScheduledTaskInfo | where-object -property LastRunTime -gt ((get-date).AddDays(-1)) |  Sort-Object -Property LastRunTime | Format-Table -Property TaskName, LastRunTime
