First record visible although grouping is active?

Hi,

I have a question concerning my actual report.

1.) Under "Row Groups" I built the following structure.

level (grouped by level column)

    status (grouped by status column)

        details (not grouped)

For "level" and status the visibility is set to "show", for "details" it is set to "hide". You can change the visibility for details through status and for status you can change it through level. If I open my report I can see that all columns are filled, although I am on "grouping level". I don't want to see details at this point.

Here is what I get:

And this is what I want:

And here is my report in VS:

Can you help me with that?

Best regards
