Things to check:
Did you you create the reporting template very recently?
Insight report templates start gathering data from the time they are created. This means that a new reporting template does not have any data in it until the report has had some time to aggregate data for the selected dimensions, filters and metrics. See Create New Custom Report for more information.
Did you chose a time period during which the campaign/category actually did receive impressions?
Did you chose a time period before May 3rd 2013?
Insight only has data available from May 3rd 2013.
Do you have any filters in the reporting template that could explain the situation?
