Merge and invisible navigation in a folder

Hi All,

I have two roles that have differents contents and each content are into a folder that I did Merge (id). The point is I want to set the property Invisible Navigation in this folders.

Is there any way to do this?

Because I tried to set these properties in my two roles, but only one content can be visualized.

Is this a bug?

Role A (first tln)

- Folder K (second tln - Invisible Level)

- iview A (detailed navigation)

Role B

- Folder K

- iview B

Regards.
