Nagvis chooses wrong icon for "host is up but has services in downtime (dt)"?

[applicakda]

Hi

I have a Nagvis map in which there is a host-icon. The host has a number of services assigned to it. All these services are in state "OK"/green, but one of the services is in "scheduled downtime" (dt). The host itself is OK/green. In this case Nagvis (IMHO) should select the icon "std_big_up_dt.png" for the host-icon (in effect green alarm-clock with a little green blob showing the underlying state of the service) .... as everything is UP but there is at least one occurrence of 'something' which is in scheduled downtime. I have inspected the web page; the icon used is "std_big_up.png", i.e. no alarm clock.

By analogy: if the same service (which still is in downtime) happens to be in a WARNING state, the host icon changes to "std_big_warning_dt.png" (=green alarm clock with the little yellow blob showing the underlying state to be in warning state).

Why IS there a "std_big_up_dt.png" icon if it is not used in precisely this situation?

Is this a bug or is there something I am misunderstanding?
