I actually have this issue as well. I brought it up here:
http://forum.queuemetrics.com/index.php?topic=624.0 but never was able to solve it.
The issue is that when running a report on a specific queue, the Agents tab displays information about every single agent that has received a call and not just the agents in this particular queue.
For example if I run a report on the sales queue and go to the agents tab, under availability it will list agents from sales, support, technology, etc. I want it to just show availability for agents in the sales queue
I am using security keys but this does not seem to be resolving the issue...
