ZohoBooks - Invoice reminders turned off by "System"

ZohoBooks - Invoice reminders turned off by "System"

Ever since I signed up for ZohoBooks, the system has been automatically disabling the invoice reminders. It's become a daily chore to ensure they're not unset now, which is incredibly frustrating, especially in a world driven by automation. Despite reaching out to Zoho for assistance and being informed that their product development team would look into it, I have not received any follow-up. 

As you can see from the pictures:

1: Reminders all turned off
2: Audit trail shows "System" as updating the reminders
3: Audit trail shows "me" turning them back on

The audit trail indicates that the reminder was switched off by the "System." Who exactly is this "System"?
