Report grouped by Activity Type shows each grouping twice
|Knowledge Article Number||000006652|
My report is grouped by Activity Type. Each of the groupings (for example "Call", "Meeting", etc.) is displayed twice.
Each of the groupings represents either the Task or the Event object. While they may seem to be duplicates, they are not considered duplicates by the reporting system. Because of this, results for either object will be returned separately.
Work around: Separate your Tasks and Events into two different reports.
