relationships problem in studio

[j.lagos]

I have the CE 5.1

I create with MB a new module which is related to other two new user modules.
I setup also the relationships between them from the MB.

When I run the application the related subpanels are not shown at all!

If I go to studio, I can see the relationships but I can't edit them, and the default subpanel box is empty.

How can I edit a Relationship into the Studio ?

(In the attached picture from the Studio, you can see details).

Thanks,
John
