Different value between old and new GUI

Different value between old and new GUI

Hello people,
I have Netflow Analyzer v. 10.2.5 and I have the possibility to switch between the old and new GUI.
I don't understand fine as work the new GUI.

For example, on Traffic/Graph what is the different between Device Traffic, Top interfaces (in speed) and Top interfaces (out speed)?
Can I change the default value from kbps to mbps as the old GUI?
Why the value of Max Speed - Avg Speed - Volume is always equal between the three different record? (device traffic,in speed, out speed)?

Thank you
Leonardo
