How to get a report with event action showing different event names?

My setup is like this:

Event Action: Agroup, Bgroup

and in each Action, I got 3 different event names: [Cap, Thanos, Thor] which turns out 6 event names in total.

The issue is that both in the event report interface and calling data from API, Cap is showing one line of total instead of showing 2 lines tagged with Agroup and Bgroup, and API is showing the total Cap values.

Is there any way to display the breakdown either on graph or data?
