Hi Amey,
From the screenshot it seems that your data is returned correctly for june.
For July, the aggregation hasn't taken place yet as you posted the message in july 1st and aggregation takes place in end of each day (for daily), end of monday (as configured in your activityReportCore_values.jpg) for weekly and at the end of the month for monthly.
If you check it today it should contain data, if it doesn't check the DB itself.
also, make sure your timestamps values are correct.
BR,
Saar
