multiple can messages for same timestamp in Simulink, using Vector VN1610 interface

Hi I'm using a Vector VN1610 Can interface. When I'm using the CAN monitor in Matlab, only 1 message per timestamp appears. When I try to do it with Simulink, after unpacking the message i have 2 or 3 messages with the same timestamp on the workspace. Any idea what i'm doing wrong? I checked the documentation, but did not find anything that helped. Attached a word file with the screen shots.
