Profile has no events

Hi, I'm using Rudderstack with a custom transformation to send events to Openpanel.

For tracking events I use something like

 if (event.type == 'track') {
    return {
      header: { 'x-client-ip': event.request_ip },
      "type": "track",
      "payload": {
        "profileId": event.userId,
        "name": event.event,
        "properties": event.properties
      }
    }
  }

This works and in the event overview I can see that all events have the correct profile but when I click at the profile and open the profile view, the profile has no events associated.

Reproduce the issue using the shown Rudderstack transformation, then compare the event overview with the profile view. Trace how profileId is used when events are associated with profiles; done means events sent with this transformation appear in the corresponding profile's event list.
