Context configuration problem on version 8.5.1

Hi,

I've configured 2 context, populate each context with a site, line and asset, and created 2 users. After setting the permission to each user to each context I'm not getting the expected result: all the users can access all the contexts.

Attached are the screenshots with the asigned permissions.

User_Fabrica_1 has not permissions to access context Fabrica 2, but in the file "Context Problem" you can see that the user can access it.

What I'm doing wrong?

Thanks.

Olatz
