That would be the name of the deployed dashboard. Have you redeployed it since making the changes?
Also, I had deployed a dashboard once, and it created a new file with a suffix after the name. Something like Ice.UI.App.CK_ShippingSchedule_1.dll when it should have been
Ice.UI.App.CK_ShippingSchedule.dll. So obviously the dashboard wasn’t actually running the updated version.
