Incorrect AIS Vector?

Hello, see attached photo for detail. I tuned on "AIS Vectors" on my e127 MFD. I would have thought that AIS vectors would show the direction of the vessel. However it appears to be showing the track. Is this correct? If so, is there a way to get it to show the AIS heading? As with the third party products it shows the heading and possible point of intersect which is very helpful to plan in avoiding a collision.
