Modified date is getting changed on help desk tickets (4311997)

In the Kace SMA Help Desk, the date/time modified is getting update/changed without users making any changes to the ticket itself (i.e. comments, status change, owner change, etc). 

It appears to occur randomly. 

• Custom ricket rule
• Ticket escalation is setup

1. Custom ticket rules
   1. Check your custom ticket rules to see when they run, whether On Save or on a schedule. 
   2. As a troubleshooting step, you can try disabling any or all rules you think might be affecting your tickets and see if the problem continues. If so, contact our Professional Services Team to receive assistance with the custom ticket rule. Unfortunately, creating or modifying a custom ticket rule is considered a "Customization" and is not a KACE support feature.
2. Ticket escalation
   1. Under Help Desk | Configuration | Queues | Customize ticket values | Priority Values, you can set an escalation time.
   2. If this is set, your tickets modified date will get updated whenever the escalation time criteria is met.
