Traffic widget is summarizing data

Traffic widget is summarizing data

Hello everyone
I need your help to create a view that shows the traffic in and out of a monitored interface.
I have generated it through the widgets but it does not show me the real data (apparently this is summarizing the data since the traffic of output is
Less than input).
I made a separation in the widget (clicking one of the values of input and output) and this would work for me but when it refreshes, put it back all the data out or in.
The NFA version is 12200 is mounted in win 2008 r2
I attached an image can see graphically
