I only Set 1 schedule on "Collect Full Inventory" weekly at 21:00 on Mon, but why Client have 2 "Collect Full Inventory" task run each time?

Hi All,

I have a All-in-One Altiris Notification Server 7.1 (Virtual Machine) for PC inventory & software deployment with MSSQL database 2008 R2.

I only Set 1 schedule on "Collect Full Inventory" weekly at 21:00 on Mon, but why Client have 2 "Collect Full Inventory" task run each time?
