Second level hierarchy in matrix doesn't work

Hi otravers,

Thank you very much for your attention and tips.

But unfortunately I had already done what you described in power bi service and power bi desktop.

In the Power Bi Service, I clicked on the Expand icon several times and it stays the same way (clickable and not greyed out).

I think it must be a configuration issue because the problem of not expanding the hierarchy doesn't happen to other people in my organization.

Regards
