The middle graph (by OS) sometime leads to AIX, not the correct OS type.

The problem is that if the OS name given does not matches the backend name, the query default back to the first in list (AIX):

Centos like that is ok:

.../secure/nodeManager/searchNodes#{%22query%22:{%22select%22:%22nodeAndPolicyServer%22,%22composition%22:%22And%22,%22where%22:[{%22objectType%22:%22node%22,%22attribute%22:%22osName%22,%22comparator%22:%22eq%22,%22value%22:%22Centos%22}]}}

"CentOS" like that (what is given by cliking in the graph) leads to AIX.
