[otrs] OTRS 2.2.1 Ticket Update...

Hello, After upgrading to OTRS v2.2.1, all tickets that enter a specific queue for escalation after 15 minutes of not being answered are still showing up as if there have not yet been answered. I have attached a screenshot showing this. In the screenshot, the ticket shows that the update time is over by 20 minutes, however, this email was answered. How can I get this to not show up unless the customer has send in another reply? Right now I have to set the ticket status to "Pending Auto-Close" because replying, adding a note, and changing the priority don't fix this. It never did this in OTRS 2.1.7, it worked as it should have and expected. Any suggestions? Thanks! -Jeff
