In Orion NPM, I have several nodes that had applications that were in an unknown state and removed the applications from the nodes. The Node status icon still shows a flashing gray box though. How do I stop this? Is this a bug? SolarWinds Orion Core 2010.2.1 SP1, APM 4.0.1, NPM 10.1.1 SP1, IVIM 1.0.0
