Data report between two networks (between two offices)

Good afternoon. How do I report traffic between two different networks?

Under "IP address groups management "I have previously created several groups (indicated the networks of two different offices).

When I create a report with only one group - the data is displayed. If I add 2 groups at once - there is no data in the report.

The data is transferred between offices, the report can not be empty.

I also have a question what the "Destination IPGroupSegmentID" and "Source IPGroupsegmentiD" fields are. Where can I find or create these "IPGroupsegmentiD" ?
