A Trend Summary report is run that includes multiple devices. The line graph that is included in the report will show 2+ devices but not all of the devices.  At the same time, all of the devices are listed below the line graph in the trend summary chart.

The Load Profile report assumes a standard logged interval of data for all included devices. If there are devices that are being logged at varying intervals it will pick devices that are logging at the same interval and exclude the others.

Resolution
The solution is to make sure all of the devices are logging at the same interval. eg. All KW demand readings will log every 15 minutes
