"Scheduled by" field in Events Module is not reporting accurate data. Help, please!

We are experiencing an issue with reporting in the Zoho CRM when using the "Events Module". The problem is that the "Scheduled By" field in the events module is not showing the field entry data. 

Example: We have a report, which should show all events scheduled by Sam; however, this report only shows accounts where there is only 1 event. It is having problems pulling "Scheduled by" field entries on all accounts with more than 1 event, not showing for those with multiple events. We are sure that it is not working because one of our accounts has an event scheduled by Sam, and when you click the event, you can see he was the scheduler, but the report does not reflect this.

Please let us know what to do here to get an accurate report.
