Reports are basically snapshots of how your team was in that certain moment. Reports take place after daily update has been done around 20:00 - 21:00 UTC.

Seems like you have won 2 team ranked games meanwhile.

The point of reports is so you can compare and see how your team has progressed. Today at the same time you will receive a new report, so you will have 2 reports and the last report will show whether you have improved compared to the last report.
