"Syslogmessages consolidated per Host" shows messeges for all hosts (PDF)

[ghost]

We are using the reports module for creating PDF files (syslogsummary).

In the PDF file, messages should be grouped by host. But by every host, the same messages are showing.

For example, below the Firewall, also messages of the hypervisers are showing, and on a webserver, the messages of the Firewall are also showed.
It seems that the filtering for the per host dos not work.

Also, when adding a filter for the Firewall, all the messages are showed (the "Report Summary" count seems working fine)

On our old server, with an older version, this works fine. Only messages from the host are showing.
