Custom report and events


I´ve been trying to setup custom reports to include data created by the tag manager.

When I look at the data through Behavior > Events and browse through the categories and actions I get completely different data when I gather data in custom reports (5-10 as high numbers and not even distributed in the same way as in Behavior > Events)
The custom report has Dimentsion Event Action and as a Metric I use Total Events.
Also use a filter based on the event category that I want to examine.

The goal is to have all the events for a specific page (page is defined with categories).

Im running the latest version of matomo-3

Anyone who has any idea about this?
