How to understand Source, Destination and Conversation in IP group?

Hi,

How to read correctly from IP group settings?

I configured IP group to monitor specific IP address, but how to read the source, destination and conversation when into IP group report?

I found the traffic volume is reversed when I read source, destination and conversation. I also read the blogs and do not have answer about how to read IP group report.
