Custom report bug? Showing unlikely data

Hi!
We are trying to create a custom report showing what the visitors did on each target page. We use the dimensions: “Target page url” and “Event actions”. For Variables we use “Unique event actions”. But the data is only 1 and that does not seem to be correct, see picture. It should be more than 1 as we have many more visitors.

Is there a bug in Custom reports and events? Or,
Are we doing something wrong here?

Grateful for any help and hints!
Best regards,
E
