3160033 - Different summaries for the notification mails in Workflow

We noticed that two emails have different headers. I was wondering if you could let us know why the headers are different. We checked our notification settings but can't figure out why they are different. One says "Signavio Workflow Accelerator Notification" and the other says "<Task A>". Could you please help us understand why there are different headers for the same action type?

The notification with the summary "<Task A>" has only one task in it, but the mail with the summary "Signavio Workflow Accelerator Notification" has more than one information in it.
Every notification for new tasks will be delayed a little bit the system as we are trying to group the notification mails to one mail. If there are notifications grouped to one mail, it could be that there are notifications for different task assignments and because of that, we are using the summary "Signavio Workflow Accelerator Notification".
