I managed to reproduce - this happens when you click on the audits button in host detail view. looks like the path there needs to be modified.
Can you please open an issue on redmine @UXabre?
you can go to the audits page directly from the monitor menu, and search for the host.
The button should either change to point to /audits?search=host=$name, or the react router should be modified to recognize /hosts/$id/audits path as a path that should render the audits page with the appropriate search - right now it only recognizes /audits.
