Thanks for reaching out.
By accident I found that this is not an issue, but just a wrong interpretion of the dashboard.
When y have a customer on dashboard y can see risks, when selected y see nothing.
When y click on the specific system (dril down) y will see the risk eventualy.
It's just that I suspected that when y click on customer level , you will see all risk for all systems.
But it doesn't.
Maybe it's just me but I find this still strang behavior.
