Over the past few upgrades I've noticed the 'Uncategorized Monitors' group comes and goes in an unpredictable way. Sometimes when I add a new monitor and don't assign it to a group the 'Uncategorized Monitors' group never appears. I have to go to 'bulk configuration' view and 'List View' to find it.
Since the 10.5 upgrade 'Uncategorized Monitors' group shows up and never goes away. Even when I remove all new monitors from it.

Does anyone have a fix for this?

Thanks
