UrBackup not automatically rerun missed backup job

I configure incremental file backup to run every day (24 hours). My backup windows is 12pm-6pm. During weekend, I shutdown my computer. I only turn on my computer during weekday.

I notice that if I missed the backup during weekend, the backup does not automatically run when I turn on back my computer on Monday morning. It will wait until 12pm to run the backup.

I thought that it will immediately run the missed backup once the Urbackup server can see my computer. But it seem that this is not the case.

Does this is how the Urbackup work or I miss configure anything?
If this is how Urbackup work, any workaround so that it will automatically run the missed backup?
